Anybody rebuild an A4LD

[jon42]

Guess i should examine more closely before i talk.The tape method worked fine.The front support is a machine fit and it was the overdrive adapter that caused the failure.It had a .007 bend to it plus i installed it backwards wich would work fine except for the increase in thrust it added because of the .007 bend and the added loss of about .003 of the recessed provision for the deeper splines of the sun gear on the correct side.

I still bet

That the #2 washer got jarred off center durring your last assembly and that is what destroyed it. I brought up the overdrive adaptor star washer for a reason. Things are pretty much fixed for spacing in the driveline. Unless there is obvious wear on the bearing surfaces there should be no need for adjustment. The overdrive adaptor appears to bend over time and the spline shaft wears into it. With a specified clearance of 0.007 to 0.025 even a tiny bend or wear will bring it out of spec. Mine bent enough to allow the washer to ride over the castle teeth. Still the #2 thrust bearing stayed in place. Just think the OD adaptor should be replaced in all rebuilds for the $7.50 it costs.

On an interesting note. Jeep has a problem with a needle bearing shattering in the OD section of previously repaired transmissions. The replacement gear assembly has welded shafts instead of swaged. The bearings rode on the welds like a roller coaster and they fatigued. Thousands of these were installed and hundreds of trained people never noticed. I have to fix this on a friends's transmission that was rebuilt by another expert 2 years ago. So it can happen to anyone!

Your talk of the jeep trans has me curious as to what its fix is.A race between the bearing and welds or grinding down the welds?Wow . I kinda feel better now.Too bad for the jeep owners tho

My overdrive gear mysteriously stopped working after some work was done on my X when it was at a ford dealership.

They said it was coincedence, removed it again (they ahd replaced a aprt that required tranny removal) and inspected it out of their own pocket, and told me the overdrive "band" is gone which was common for this type of tranny, but I'm no worse for wear.

They said the tranny still had alot of life left, jsut that I'll be basically driving in regular D instead OD. 2-3 mechanics had looked it.

Where they pulling the wool over my eyes? My tranny still shifts fine and engages properly.

 

[jon42]

The O/D band is only a $6 part for the ford dealer.You,d think they would have replaced it considering how much effort it takes to remove a trans.Any prudent mechanic would relace it considering the minute cost to them.Since the band only appleis in O/D, you would observe slippage in that gear if not.

That's a cute story

But, I wouldn't believe it. They might have adjusted the OD band wrong. There are two bands that can be used in the overdrive, single and double overwrap. If they tightened the double to the single spec, that could burn it out. The 3-4 solenoid could have got some dirt in it. Maybe the band broke. If they replaced anything more than the front seal I would suspect sloppy work. Keep watching the fluid for color changes.

A4LD tools

On the subject of trannie tools, I think the best advice is that some tools are "nice" to have, but can be easily worked around (most all bearing seal installers fall in this category for example) some are such overkill you wonder why they invented em, and some are must haves or incredible time savers (like an installer for an overrunning clutch on a recent Chrysler rebuild I did. Took me hours to work around a 5 minute job with the right tool). I haven't done my A4LD yet, so cannot comment, but I'd suggest that if you want a cheap set of tools look for them on E-bay. I've purchased entire factory toolsets (like the 74 C-3 set that includes the center pump alignment tool) for less that what the tool would cost new elsewhere. You are looking for rotunda toolset 74P-7000A I think (it's the C-3 set). Also, for what it's worth, ATSG does not write the Ford manuals, they copy them and sell the reprints.

Lost overdrive

I have a 93 limited. Driving down the freeway started going up a hill tranny down shifted, made it up the hill when it shifted to od there was a little pop and it shifted back to 3rd. Coasting down a hill it acts like it is in neutral. I can shift through all the gears and the engine does not hold it back. Any ideas would be helpfull. thanx in advance. Forgot to add I repaced the modulator it had fluid in it

No Engine Braking.

overdrive planetary broke at the base of the oneway race. Its one of the first things you see when you open the case after the pump is removed. Good luck and have fun with it. If you fix it yourself, even if you dont get it right the first time you will feel like you really accomplished something.

 

[moabjer]

thanx for the info i'll probably pull it next week

sorry to get off topic here but i didnt want to start a new thread for this simple question. I have a 94 xlt which is on its 6th a4ld and running well, but last time i brought it in do be replaced on the recepit from the trans shop it said 5r55e on it is it possible they knowing my history(becaus i told them) changed it out from the a4ld to a 5r55e? is this even possible?

 

[Glacier991]

Short answer, anything is possible, but to do that would have required MAJOR electronics changes in your explorer and a few added sensors and completely different computer. Didn't happen.

 

[thewishkah]

ok thanks for the info
