trans removal - HELP!!!

[JQ-72]

Well, my transmission gave up over the weekend and is time to rebuild. How is the easiest way to drop the trans? Unhook T-case or drop it with the trans? Thanks for any help. Oh yeah, it's a 72 K20 with TH350 and NP205 and 4" lift.

If you don't have a good trans jack, then you had better separate the 2. You have to pull them apart anyways to have it rebuilt

[1969K10]

if you pull them apart, you can man-handle them out. if you leave them together, you need a jack to get them out...

i take mine out seperate....and i still use a jack. I made a fixture that fits my jack that holds the transfer case.

One of the handest things i ever built was this trans a transfercase stands for my 3 ton jack.
I have one built for the sm465 and 205 transfercase thats out on lone right now.I just take angle iron and weld it were it needs to go to for support. Then one just has a round stock welded to the end for auto trans. There to good i have a hard time keeping track of them from everyone coming to get them to borrow.

Cool idea, better to use the mind than break your back!

[OLDCHEV4X4]

My tranny fixture looks alot like that. But my TC jig is smaller so i can get up close to the crossmember and still balance the akward thing on the jack. And it has a angle iron "bridge" welded to one end to hold the driver side of the TC up.
I also cut the heads off some 3/8 bolts and put a point on them for line up dowels.

How did you make out ?

I used an engine hoist. Went in through the passenger side. It was totally painless. Easy one man opperation.

That is so simple it's genius! I'll use that idea next time.
I've always resorted to the old block of wood on the floor jack trick. It works ok with two people but a nightmare by yourself. There is nothing like laying in a pool of burnt tranny fluid. While you use a wrench on the bell housing bolts with one hand. While the other balances the tranny on the floor jack. As you simultaneously operate the jack handle with your foot. Good times

[jimi121v]

Mine is a manual trans, but it should work with the slush box too.

[JQ-72]

Well, I got it done easier than expected. I put a floor jack (and block of wood) under the T-case cross member, leaving it attached to T-case. I unbolted the cross member from the frame and pulled the T-case straight back from the trans. I rolled the jack slowly and the T-case stayed on the jack and out of the way for trans removal. I had a block of wood on the oil pan to keep weight off the motor mounts. I then removed the trans just like a 2wd - lowering it with another jack. Thanks for the input and I'm back on the road again!!!

I am having a really hard time getting my SM465 tranny out. I think I have everything disconnected: front and rear drive shafts, Cross member unbolted (trying to remove the transfer case and tranny together) Speedo cable is off, two other electrical wire plugs disconnected, the shift lever is removed and all four bolts from the bell housing to the engine are out. I just need to slide it backwards to replace the clutch but I can barely budge it. I have three floor jacks to support everything and tried raising an lowering the everything to get it to move but nothing is working. Any ideas? I think I'll separate the tranny and transfer case and maybe that will help.

Did you remove the two bolts holding the 205?There is a bracket mounted on the pass side frame rail that holds the two bolts.

[Toddski]

I don't see the bolts you are referring to. Unless you mean the two that bolt the cross member to each frame rail (drivers and passengers sides)? The transfer case appears to be free. My transfer case is a New Process Gear 208 so maybe that's the difference.

[68panelman]

Thats prob why,the 205 has 2 bolts that mount horizontally on the side behind where the front output is.

if i remember correctly there are 6 bolts holding the bellhousing to the block not 4

[OrrieG]

Here is a photo that shows the bolts connecting the trans to the block, 3 per side, 6 total. It is held in place by two pins to, it has to come straight back about 3/4" before dropping. If you let it sag it can bind up. I assume you have the torque converter unbolted too?

[Toddski]

Do you guys know if there is any reason I should pull any bolts that connect the bell housing to the tranny? I spent a while today trying to figure out what's keeping the tranny from coming out but no luck. I didn't take the transfer case off yet and hope to avoid doing that after looking at it further today.
Thanks for the tip on the motorcycle lift PPMT, I don't have one but I can see your point.

[mudmizer]

Toddski, If I follow this right you have removed the 4 bolts that bolt the 465 to the bellhousing, you dont need to remove the 6 holding the bellhousing to the back of the motor. Sounds to me like you might be getting a bind in the clutch fork and throwout bearing. These can bind on the output shaft from the tranny if not pulled out straight usually you will feel a springing type bind (if that makes sense), but pulling the case and tranny out as one piece you may not feel that. If the fork is still in the bellhousing take it out, pop it off the fork ball (there may be a clip) and pull the fork out the side. The tranny and case should then come back.

If this is whats binding.

[Toddski]

Thanks for the help guys, this is really great. Unfortunately I've had a bad case of the Flu for the past week and haven't been able to wrench on my truck. I hope to be in good enough shape to get after it again tomorrow.
OrrieG - My SM465 is a manual so no torque converter. Thanks for the photo diagram.
Mudmizer - I removed 4 bolts that hold the bellhousing to the block, but from what I'm hearing their should be 6. Not sure how to remove the bellhousing from the 465 without pulling it from the block. I need to replace the clutch anyway (my whole reason for pulling the tranny).

[Toddski]

Well I found two other bolts near the top of the bellhousing holding it to the block. Once I got those out the tranny came out. Thanks to everyone for your help.
