Re: Complete T5 swap thread - one way to skin the cat
Hi guys!
I am putting a s-10 t5 in my `61 Apache with a 283, I have all the parts needed except for the clutch. In my truck now I have a 10" clutch. It is quite worn (both pressure plate and disc) and I want to change it. I understand that many choose to use a 11" clutch from an Astro van. Will that pressure plate fit my flywheel? If not, are there any 10" clutch kits with a 14 spline disc that would fit my truck? |

Re: Complete T5 swap thread - one way to skin the cat
One more thing... Is the bolt pattern on the 10,4 clutch the same as the 10"?

Re: Complete T5 swap thread - one way to skin the cat
I believe that the best bet is to go with a clutch set that matches what the transmission came from. I bought a clutch pack for a mid 80's camaro. Not yet at the bolting it up point... So not 100% certain it is the right fit, but i am 99.9. Not sure this helps...

Re: Complete T5 swap thread - one way to skin the cat
That was my plan at first, but the s10 clutch is smaller, I think itīs 9 1/8" or something like that. Iīm not sure about the Camaro clutch. Perhaps itīs bigger.
If my pressure plate would have been in a good condition I guess that I would have settled with just changing to the smaller s10 disc. Thatīs why I need to know which clutches have the same bolt pattern. Thanks for your reply and good luck with your swap! |

Re: Complete T5 swap thread - one way to skin the cat
Astro 11" clutch disk will fit on the stock v8 flywheel and inside the stock bell hsg.
Highly recommend buying an astro van 11" KIT, which includes disk, pp, and release bearing for reasons stated earlier in the thread - proper stacking height of the combo. But generally speaking - as CRGRS pointed out, it's important to buy a clutch (kit) that was designed for the trans you're buying it for, not the vehicle or the pressure plate, etc. This ensures proper spline count, among other things. It can be made to work by piecing together parts, but I had enough headaches already, very glad I went with a complete kit when it came to the clutch disk/pp/release bearing. Known combo that works. Just a recommendation, many ways to skin the cat, as the thread title implies! Good luck, hope the install goes smoothly. |

1964 I6 230 short step I pulled my 92 Camaro WC T5 to put a S-10 tail housing on it. With the shift plate from the S-10 on I can't seem to get it to shift into 5th or reverse no matter how i set up the top plate forks. Any ideas? Thanks Larry |

The trans was in my 64, put on the S-10 tail housing to make room for a console (bucket seats). It is sitting on the bench & not installed because of the problem with shifting. It has been rainy & cold here so I haven't been back out to the carport. Larry |

Re: Complete T5 swap thread - one way to skin the cat
Was the Camaro T5 already in your truck (with a Camaro tailshaft on it)? Or, are you saying you pulled if from your Camaro(?) to swap on an S10 tail and then put it in your truck?
Did you use the stock truck bell housing or the Camaro bell when installing in the truck? Does it feel like your stick is binding on the hole you cut in the floor? Reason I ask - Camaro Bell Housing mounts the trans in a canted fashion, and then a Camaro stick is canted the other direction to compensate (so that it comes up straight through a Camaro console (in a Camaro) closer to the driver with a short stick). There can be interference problems if you use a straight S10 stick on a canted Camaro trans+bell combo. However, if you used the stock truck bell, this shouldn't be your problem. If you did use the Camaro bell hsg, then buying a Camaro-specifc shifter may solve your problem, because it will compensate for the canted mounting of the trans. But it might be better to just use the stock truck bell housing and a straight (S-10-type) stick. The big question to answer is whether or not your stick is impinging on the opening you cut in the floor. I assume it's not, but that is the only issue I can think of. Beyond that, I could only imagine this problem is internal to the trans - perhaps something got jacked up when swapping on the tailshaft - since that is really the only thing that has been changed recently. You may be onto something with the question regarding internal fork problem. Sorry, not sure that is much help, but all I can think of based on the description. |

Re: Complete T5 swap thread - one way to skin the cat
Hmm, in that case Larry, I can only assume there is an assembly problem in the tailhousing - if reverse and 5th were fine before, then the only thing that has changed is the shifting linkage inside the tailhousing from the S10. Do you know if the tailhousing came off a working trans? If yes, then it's got to be an assembly problem (the mating of it with your trans) or if unsure, then it could actually be a defective part even if you assembled it correctly. Sorry, but we're now getting into the innards of the T5 and that's where I start to walk around in a dark room feeling for the walls... I do have a T5 assembly manual in .pdf format I can send you if you like. PM me with your email and I'll send it. (there was a link in this thread, but I think it has gone dead).

Re: Complete T5 swap thread - one way to skin the cat
Got it back together. Can't for the life of me figure out what I finally did different. All's well that ends well. Thanks for the input.

Re: Complete T5 swap thread - one way to skin the cat
HERE is a link to download the T-5 service manual.
Now if only I could figure out what the correct bell housing is to mount my WC T-5 (out of a Camaro) with a Hydro clutch to get my shifter straight! Already have the S-10 tail shaft. |

Re: Complete T5 swap thread - one way to skin the cat
thx for posting the link BAT. I agree with brokenspoke, use the one that came with your truck - it will orient the camaro trans "straight up" (i.e. you won't incur the frustrating camaro "tilt/twist") and you can route your hydraulic hoses through the hole where you will have removed the shifter rod and its boot. That is, if you HAVE to have hyd clutch, etc - it is not required at all, you can use the factory stuff and that saves a lot of headache. But, if heart set on the hyd release bearing, etc, then you can still use the stock bell.
One more note - if you use a stock bell - you must use an S10 shifter (both are straight) if you use a (new) camaro bell for some reason - you must use a camaro shifter (both are bent, opposite directions - so that the stick still comes up straight). |

Re: Complete T5 swap thread - one way to skin the cat
To Jocko and all who read this wonderful post.
A friendly word of warning, SOME OF THE POPULAR T5 INTERNET SITES ARE STILL FULL OF INACCURATE INFORMATION. As for me, I'm totally sold on the idea of putting a T5 in my 1965 C10 with a 3.73 rear. Yesterday, I went to the salvage yard and pulled a T5 from a 1989 GMC15. Info that I had from the internet confirmed that it had the gearing I wanted. Unfortunately, I've come to learn that the internet info is VERY UNRELIABLE when it comes to telling you what the gears inside are. A majority of the websites said the tranny I had pulled had a 3.76 1st gear and a 0.72 OD gear. WRONG. Got it home, opened it up and spun the tailshaft a full turn and watched the input shaft turn a good bit more than 3/4 turn. So I actually have a 0.86 OD and that just will not be good enough for my 3.73 rear. I can return the tranny and get a refund. I wasted some time but I got some experience and knowledge along the way. Just trying to help my fellow truck owners so they can be spared from the same frustration. ![]()

Each tranny has an ID tag. The tranny I pulled had all the proper tags and they were readable. That is the BEST way to identify a tranny. However, several VERY popular links on the internet gave INCORRECT gearing ratio information when I matched up the ID tag with their charts. Bottom line, VERIFY EVERYTHING by CHECKING THINGS YOURSELF. Some guy says he has a tranny for sale with such and such gearing. Fine. He's probably basing his information on one of the websites I used AND HE COULD BE WRONG. That will be true for eBay, CL, or a swap meet. Just imagine how frustrated I'd be after installing my tranny if I had not found out the TRUE gear ratio. I'd have wasted big money and time all because of misinformation. Just be sure to verify everything yourself, and not based on some website chart. Am I preaching? Yep! ![]()

Re: Complete T5 swap thread - one way to skin the cat
Hoping Jocko and the experienced others can chime in and help clarify some things for me:
I have a 1968 C10 with a 3 speed Saginaw column shift 250 I6 Gear ratio is 3.42 with 29" Tall Tire I am in the same debate with myself as I have seen across Jocko's numerous posts and research threads: To Go T5 vs TKO 500/600 Regarding the T5: I have only been able to locate the S10 T5's that are Non-WC and have the below gearing 1352-201 GM 1990 S-Truck P 1st-4.03 2.37 1.49 1.00 5th-0.86 I am concerned that low of a 1st gear will just disappoint me and be almost useless - Anyone have any comment with this low first gear or the 3.76 options usability OD @ 70 I should be in the ball park of 2300-2500 (Which I have read the 250 operating range you want to shoot for is 2000-3000) Does this seem like a good area to be in? I also have some additional questions about the parts needed for the T5: - What bellhousing hole diameter should the 1968 model truck have? - is it the 4.686" dia index ring or the 5.125" index ring on a 250 - Flywheel: You keep and use the stock flywheel for your truck? - Clutch / Pressure Plate / Throwout bearing: I'm alittle confused on these parts I have seen the mention for Astro Van clutch in multiple threads on here and the HAMB Jocko recommends using the entire Astro kit for a V8 flywheel Will this same situation apply for the 250 I6 flywheel Or is it the other situation where I should go with the kit from the vehicle the transmission came from Spacer Plate and Bearing Retainer Mods: I understand the need for these - I was planning on Hot Rod Works spacer plate depending on what diameter bellhousing I have - http://www.hotrodworks.com/catalog/i...1983-cars.html I am really trying to debate whether i should move forward with the S10 T5 or go ahead and invest in the TKO and the future upgrade possibility. The 250 is a strong motor and I plan on keeping it, but eventually ( i dont know when) down the road I think i would upgrade to a LS but that part is not top priority on the build list Jocko Mentions he has about $1k in his swap vs the $3k mark for a TKO http://67-72chevytrucks.com/vboard/s...d.php?t=473871 Getting alittle intimidated and lost in all the small details |

Re: Complete T5 swap thread - one way to skin the cat
I Have a 1986 chevy LWB pickup with a 3 speed manual. It was originally a V6 and it has a hydraulic clutch with an external slave and fork. It has a tired 350 2barell in it now, compliments of the previous owner. I was told the 6 had some sort of mechanical failure. The idea of moving to a floor shift and getting a highway friendly gear seems like a good idea to me. This is my parts, building materials, running, hauling truck. so I don't want it to be down for more than a week or two. Preferably do the swap in a weekend. I looked at the TKO600 5 speed but 3000 is a little steep. I t is just a half ton pickup. I have not seen anybody talking about swapping transmissions in these square bodied trucks.
I guess I need to start shopping for a transmission. archie =) =) =)

Also, my truck is about 330 hp and 400 lb/ft at the crank. I have had zero issues with the trans holding up. I kick the crap out of this thing on a regular basis, I should say I only have a open diff though. I have had mine in since September and I love it. My t5 is a 3.76 1st gear and it goes great with my 2.73 rear end. Runs about 1750 at 75 MPH. Also I used a large hole bellhousing. Keep in mind if you cant find the smaller hole bell that these trannies are cheap, if you pay more than 300 you got bent over and no reach around, so who cares if it wears out at 20k instead of 150k. Good luck Buddy! Last edited by silversnail86; 02-25-2013 at 08:31 PM. Reason: forgot stuff |

Below is an rpm comparison for you with your prospective T5's specs (and 29" tire). My T5 had a 3.97 1st gear with a 3.73, so almost the same final drive ratio for 1st gear. This was a BIG concern for me, but it turned out to be not that big of a deal. I could start off in 2nd, but for me personally, 1st gear is what I normally used - I had to shift pretty soon after starting - about 3/4 of the way thru a big intersection, for example, but it was ok for me. For your tastes, you'll have to judge for yourself, but it was less of a problem than I thought it would be. I'm not sure which bell housing index ring is stock for a 68 - but if it is the large one, you can use one of these to correct the problem (i.e. the good news is that the T5 has the smaller dia, so you can adapt): http://www.advanceadapters.com/produ...-down-to-4686/ (it's an index ring reducer from Advance Adapters - $25). I bought a new stock flywheel for the engine I was putting it onto (a 283 in my case). Probably need to have someone confirm that your I6 has the same or both bolt patterns on its flywheel before buying. An I6 guy on here could probably answer that - I don't want to say that the Astro Van pressure plate will bolt directly to the stock I6 fly if I'm not sure of it. it is NOT the case that you should buy a flywheel to match what the trans came from - that's not relevant. The key is two-fold: a) the flywheel must be able to bolt to your crank, and b) the pressure plate you buy must be able to bolt to your flywheel (and the clutch disk and release bearing should be matched to the pressure plate - that's why I recommend a kit) The spacer plate you posted a link to is a nice one. This one also works (and the Vintage Metalworks guy is very helpful and informative if you have specific application questions): http://vintagemetalworks.blogspot.co...ter-plate.html My advice: might consider continue searching for a different T5 (if you choose the T5 route), because the .86 o/d is not a lot of bang for the buck (BUT, keep in mind that a 3.42 is already a very highway friendly cruising gear, so this might not be a bad thing after all....). While the 4.03 1st gear doesn't sound ideal, it's doable with a 3.42 rear gear. What you have will work - but I'd only do it if you are comfortable with the 1st gear and cruising rpms you see in the table below. However, if you plan on hot-doggin the future LS at all, I'd also recommend skipping the non-WC (or even a WC) T5 and save the 1-time pennies for a TKO. Any T5 won't last long if you like to dump the clutch and do burnouts. Hope that helps! |
