Qs about pulling a tranny

[AZTY]

I think my torque converter is going out. I have been having a problem where the ty won't shift till like 3000 rmps no matter how fast I am excelerating. I was spooling at a light, showing off, and after that, bigger problems. If I am stopped, it won't engage and start moving forward until I rev on it a little. Then, if I stop, I can feel it dis-engage. I still have the problem with it shifting gears high. I tried to excelerate hard from a stop and it made a noise like if you grind the gears in a stickshift.
Well here is the problem, I no longer trust any place to work on my truck (because of too many previous problems). So, me and a buddy started to pull out the tranny yesterday but ran out of daylight, so I plan on finishing it today to where I can get the torque converter out. So I disconnected the two electrical plugs, all six bolts that go to the cross member, disconnected the front and rear drive shafts(the front fell down, but the rear seams to be stuck together), and taken off the converter cover. All I think I need to do today is drain the trans fluid and disconnect the tranny from the motor. My questions are:
1. Is there six bolts that hold the tranny to the motor?
2. Do I need to disconnect the tranny lines before I drop the tranny?
3. Does the rear drive line just pull out the tranny once its disconnected?
4. Once the tranny is sepperated from the engine, will the TC just pull off?

Any info on this would help, cause this is definately going to be a learning experience for me. Thanks guys

Re: Qs about pulling a tranny

1. Is there six bolts that hold the tranny to the motor? yep
2. Do I need to disconnect the tranny lines before I drop the tranny? yep
3. Does the rear drive line just pull out the tranny once its disconnected? pull out the rearwheel driveaxle first
4. Once the tranny is sepperated from the engine, will the TC just pull off? it should put you are better off, taking the 3 bolts out of the flywheel
don't let the tranny hang on the engine to get to the 2 upper belhousingbolts, or you might destroy you dist where it'connects to the oil-pump

take out the crossmember and you are able to move the trans with the transfercase attched (and propshaft)

Any info on this would help, cause this is definately going to be a learning experience for me. Thanks guys

There were a good post on this from George Blake. It was in the tech articles section...

1. Yes.
2. You are not actually removing the tranny so it may not be necessary. Unbolting the tranny lines from the radiator should give you enough play to get the torque converter out.
3. Yes the driveshaft slips into the rear of the tranny. You may need to slip the driveshaft out so that you can back the tranny up to pull the torque converter off.
4. The torque converter is bolted the the flexplate which in turn is bolted to the the crank. I think you'll find it easiest to unbolt the torque converter, slide the tranny back, and then the converter will slide of the tranny splined shaft.

What about the Dip stick? Do I need to disconnect that?

Yes it has 1 bolt holding it to the block best I remember but my memory is pretty damn bad.

Oh yeah. You can just pluck it out of the tranny. I think there should be enough slack in the tranny shift cable (whatever the cable is called that goes to the throttle body), but you can give yourself slack by unhooking it from the throttle body too.

Phil is right....I dont use that bolt anymore

First things first, make sure that you disconnect your TV cable or else it WILL get damaged during the pull. Just pop off the cables and compress the plastic tabs that hold it into the bracket on the intake.

1. Yup, there are six 14MM bolts that hold the trans to the motor. The bolt that holds the brace that goes from the tranfercase to the bellhousing can be a PITA to get out. It's close proximity to the sheet metal makes it hard to get on with a socket. A cut down combination wrench comes in handy for that one. The *real* challenge is the top most bolt/stud that holds on the bracket that the downpipe bolts to. I have a 14 MM deep weld socket that I cut down just to get that one off. It's the same situation as the transfercase brace, I cut a notch in the sheet metal afterwards and all has been good on my two transmission pulls.

2. It's not necessary but you may *want* to especially if your lines are looking kinda rough. I was bolting up my tranny cooler in my S10 daily driver and one of the lines split when I was manipulating it. Had to remove Y-pipe, remove driver's side exhaust manifold and drill out exhaust bolt that snapped when I was removing Y-pipe to replace the transmission lines. Bend lines to fit where the stock ones did etc, etc, etc...

3. The rear drive shaft can get "froze" if it has never been removed. The easiest way I have found to break it loose is to CAREFULLY pry on the driveshaft against the yoke on the rear differential. A small pry bar or large screwdriver will work. I always give the bearing caps on the driveshaft a good coating of grease to keep them from sticking in the future BTW.

4. There are three bolts that hold the torque converter to the driveplate. You will have to remove the torque converter inspection plate on the bottom of the transmission to get to them. The best way that I have found to remove the bolts is to use a combination wrench and hit it with a LARGE hammer. If you just try to muscle them out, the TC will just spin unless you have some way to hold it. On top of that, there is orange thread locker on the bolts keeping them in too. A large flat head screwdriver helps to rotate the driveplate so that you can get to the bolts. Simply insert it into the mounting pads on the torque converter that hold it to the driveplate. Only problem is, you won't have enough room to fully rotate the driveplate to get to the next bolt... I use a small pry bar and pry the teeth on the driveplate against the nose of the starter motor to get the extra rotation that I need to get the screwdriver in the next mounting pad on the torque converter.

In closing, it is VERY IMPORTANT you use Loctite 262 (the red stuff) or equivalent on the bolts that hold the torque converter to the drive plate! Also, the relationship between the torque converter and the bell housing MUST be about 5/8 of an inch to the mounting pads or else you WILL damage your pump when you *try* to bolt the transmission back up. I use a aluminum yardstick cut down that will fit across the face of the bellhousing and measure how far the pads are from it. Pulling a transmission in our trucks can be a real challenge but take your time and you will be fine. HTH's

Removing the torque converter bolts is *significantly* easier with a friend manning a breaker bar on the crank pulley. He can turn the engine over for you also so that you can get to all of the bolts easily.

!undo the motor bolts,tc bolts, undo the tranny mount and yank it back. i might be able to help you beggining of the week if you cant get it.

True. However, I do all my pulls by myself in two hours flat start to finish :wink:

What do I need to do to get the six bolts off that connect my engine to my tranny? I think I see four bolts, two on each side, but if the other two are on the top, I have no idea how to get to them, what do I need to take off to get to them?

 

[Ian Turgeon]

Doing mine, once the xfer case was off, We could angle the whole motor/trans back to get a shot with some long extensions and a wobble.

 

[SY2932]

Extensions and a flex socket from Craftsman will be your new best friends :wink: . You will have to play some "syty twister" under the truck to be able to see the two topmost bellhousing bolts. Removing the transfercase isn't required as I helped a bud swap out the TC in his ty and we did it without removing the transfercase. With regards to reinstalling the bellhousing bolts, the one on the top passenger side is a real PITA. Because unlike the other bellhousing bolts, it is not flanged. This is because it uses the dipstick tube mounting tab as a washer. Trying to get that bolt back in the hole, through the hole on the dipstick tab and a clip for the wiring harness will try your patience. It helps to have small arms and be able to reach back behind the motor from the top...

Here's a link to a "how to" from my mentor: http://www.sytyarchives.com/howto/viewarticle.php?article_name=trans_removal.php&dir=drivetrain Also, if you have what you are supposed to have holding your TC inspection plate on (I have seen a truck that didn't have one), one of the bolts will be a T40 torx head IIRC. Don't try to use a hex head or chances are good that you will strip it out. HTH's

A WRENCH or SOCKET !!

You need a super long extension and a universal joint. If you go back towards the transfer case end of the transmission and look down the top, you can see the top 2 bolts.
