So I knew that the '70 SWB C10 we bought was kinda cobbled together but the price was too good to pass up. We knew that the PO had stuffed a T5 trans in to it and it seems to be OK, my biggest issues are the long throw of the shifter and how far back on the high hump the shifter sits,
So my question is should I keep the T5 or should I replace it with a GM trans? If I replace it, was there a 4 speed option (I know about 3-speeds)? |

Re: What Is The Best Trans?
I don't know if they'll fit easily but the modern truck 5 speeds seem nice to drive.

Re: What Is The Best Trans?
I like that option (yes I want to stay with manual), anybody know what trans that it and will it bolt up to a SBC 350? I am rebuilding the rear end but I think I will wait to complete that until I figure out what my final trans will be so I get a good match for the ratio.

I have a 72 long bed with 3 speed on the column. It winds up pretty fast - sometimes you can shift from first to third and go on. I would like to have a five speed for it to have less RPM on the interstate. The other options are a 700R4 automatic or a 4 speed manual from a car.

Re: What Is The Best Trans?
I have a 700R4 in the Longhorn. I thought he wanted manual.
I like the 700R4 for an auto but there is a lot to do for replacing a TH350. A good choice there is a built up metric 200. As long as you have a stock motor. The driveshaft will have to be changed if you are manual now as well as adding a tranny cooler. I like the 700's low first gear with the 4.11 rear the truck has.

Re: What Is The Best Trans?
The T-5 is a great choice as long as you don't torture it. You can get a short throw shifter for it.

Re: What Is The Best Trans?
If I go back to a SBC I'll go with a 200-r4 Raptor. They are the same size as a TH400 and easy to build to handle 400HP. They have the same gear ratios as a 700R4. The long tail shaft on my current 700r4 makes my front driveshat a bit shorter than I like.

Re: What Is The Best Trans?
If you want to know what your cruzing RPM will be at 60 or 70 mph,go to ringpinion.com.Go to calculators,enter your rear tire diameter & ring & pinion ratio.If your trans has an overdrive you will need to factor that into the ring & pinion ratio.

Re: What Is The Best Trans?
You may have a GM trans just one out of a Camaro but that is a good thing. Now find an S10 T-5 and change the tailhousing and shifter top and move the shifter to the end of the center case , it will move forward like 8 inches. Do a searh on here there are plenty that have done it . I plan to do the same .I already have both T-5's. Jim

Then I did a search for S-10 Trannys to look at the configuration (looking to do what hugger suggested) and it would appear that my shifter already sits to the rear of the center case like mentioned. Here is a pic of what mine looks like... any thoughts? |

Re: What Is The Best Trans?
Well after some research it would appear that I have good new and bad news... The good news is that I do believe I have the S10 tail shaft. The bad news is... it's for an electronic speedo! After seeing what the cost is to convert from electronic to mechanical, I think I may just keep what I have but search for an older S10 tail shaft and a new shift kit.

Re: What Is The Best Trans?
Don't get to upset just yet BAT there are ways to intsall a speedo gear where your reluctor ring is on you tailshaft effectivly changing it over to a mechanical speedo. I amsuprised that when you did your searhes on here earlier you did not run across the post about that as well. I think a short throw shfter is gonna change your life. Each piece of that whatever that stuff is added to the shifter top is gonna add distance between gear throws. Now while I will agree that added length will be needed to have a decent length for a shifter what you have may be more than needed and on top of that the S-10 shifter is not really known for its short smooth throws. An aftermarket shifter is availble if you decide you want to go that way and they have internal adjustable shifter stops to reduce the throws that much further[do some limited degree]. Jim

Re: What Is The Best Trans?
just a thought they did use a sm465 4 spd on these trucks. First gear is a creeper though. Here are the gear ratio's.
First Gear - 6.55:1 Second Gear - 3.58:1 Third Gear - 1.70:1 Fourth Gear - 1.00:1 Reverse - 6.09:3 |

Re: What Is The Best Trans?
A shifter for a Mustang won't fit. I use Cameros.

Re: What Is The Best Trans?
I installed a 4L80e in my 69 swb and it fit like a glove with little trimming to the dog house. Seems like it will work fine with 1/2" of clearance between the top of the trans and the bottom of the cab.

Re: What Is The Best Trans?
Well I think for now I am going to stick with the T-5. To overcome my electronic speedo issue, I just bought a full S10 trans with a mechanical speedo (now those seem very hard to find). If any one is looking to do a T5 install and needs an S10 rear housing and trans cover (what you need to move the shifter up), I will have one available soon.
Also found a short shift kit for it here and I think I will be using this shift lever. The only thing it sounds like I need to do is to be sure that I have them install the adjustable stops on the short shifter to save the stress on the gear box. Thanks for all the responses and Merry Christmas!! BAT |
