1988 760GLE Transmission inquiry

[DeRail]

As for the trans additive, should I add this ASAP since I didn't put it in when I drained it two days ago?

If you still intend doing another drain/refill or a flush in the near future wait until then.

Don't mean to come off as annoying, but I do get worried over making sure that things are changed at the correct intervals. But, by in the near future, does that mean that I could go until the next drain in 20k miles? Sorry, I don't want to go overkill but at the same time want to make sure that I'm doing the required maintenance for the autobox.

I'll throw on the spare and see how it drives. If I'm still having problems then off to the tire house we shall go

Thanks Bill,
Darrell

by in the near future

In an earlier post you mentioned 500 miles.

If you are going to miss out the flush then, for your peace of mind, put the additive in now. You only need to drain fluid to the amount of additive. If more fluid comes out accidentally then top up as necessary.

I think I will pass on the flush, I did rethink it a bit considering that the mileage is > 100,000. Will throw in the additive and check the tires and get back to you.

Thanks

I would be tempted to leave it until the next service is due but that is your decision.

This is from my little cheat book and the spelling mistakes are not mine:

Sorry to dig up such an old thread, but I did have some questions. I was cleaning the throttle body tonight and noticed that it looks like the fill tube can come right down through the engine bay provided enough clearance. Can anyone confirm that the tube and pan can just be pulled down as one piece when equipped on the B280F? I was under the impression that for this to happen on the 4cylinder 700's, the starter would need to be removed. I plan on cleaning the pan and strainer while it's out.

As for the snippet from your cheat sheet Bill, re-reading this, it seems that it describes the "flush" technique I mentioned earlier which is to use the return line to purge the box of old fluid. I thought that you could use the return port on the radiator rather than disconnecting the return line at the autobox. Would such a procedure still be advised at this mileage? I dont mean to keep asking, but considering the variables in the problem have changed, I figure it couldn't hurt to ask.

Thanks!
Darrell

Whilst looking for inspiration I came across this TSB dated December 1990:

760 ATF filter cleaning.pdf

(320.47 KiB) Downloaded 199 times

If you go with this you don't need to worry about the tube and pan.

The drain/refill is just that. To flush the system you would need to put a lot more ATF through until it ran totally clean or use a power flush - not recommended for high mileage vehicles.

Bill, you're awesome!

As noted above, I did a drain/fill last november. I never did the other drain and fill within the 500 miles, before classes start this semester I will do another drain/fill (my commute is all stop and go traffic) and add the appropriate amount of the Lubegard product.

I'll keep everyone posted!
Thanks,
Darrell

Well, it's actually a 91 wagon, but I have a question about the tramsmission pan (or sump, as Bill calls it). The back of the pan has two screws that are unreachable due to a piece of metal that stabilizes the exhaust pipe, at least I think that is its function. How do you get this brace out of the way? Is is two screws on either side of it, or the one screw further to the back of the car (that is reached through an opening in yet another, much larger brace- transmission brace, I think)?
I'm trying to reach the transmission kick down cable. I figured I might as well flush the tranny at the same time. And so while we're here....how much has to be taken off/apart in order to get to the job fishing that cable out of the transmission?

I remembered reading about this in the Volvo FAQ when doing research for the transmission drain/fill.

It seems in '90 models and later, there is an "intermediate exhaust bracket" that goes right across where you need to access.

This page in the FAQ tells you the procedure for doing a pan drop on your model and there's an entry on there for the kickdown replacement as well.

Yep, my worst fears have been realized.... (not really my worst fears, but certainly a big job for my weekender self without a garage).
This is an excellent write up and I plan to eat my Wheaties and give it a whirl this weekend. I still love my Vulva, I mean Volvo, but it does give me some headaches these days.
I sprayed the flange nut tonite and will let it soak for a few days.
You guys are awesome for providing this level of expertise. Thanks.

Ok, working only on the weekends, I'm still at it- we've had two straight weekends of rain here in VA and I just got into the tranny tonite after work (obviously my first problem is not having a garage).
I did not remove the filler tube from the pan but loosened two bolts that hold it in place as it comes up to the top of the motor. This allowed the pan to fall down enough for my purposes.
There were two brackets that needed removed- the exhaust bracket and a tranny bracket. This allowed access to the last two pan screws.
Now, I'm still short of removing the trans filter- is it just four screws to remove it?
There's still very little access to the kickdown cable pulley. I have an inch and a half window on the side to view the pulley and obviously very little room to work. Does removing the transmission screen provide a hole to reach up in and across to the kickdown cable pulley? Or does this whole bottom piece to the transmission (what you see when you remove the pan) need to be romoved? If so, there's a dozen or so screws- which ones need to be removed?
Evening fell quickly tonite (welcome daylight savings!), and I ran out of light. Definitely not enough of an opening for a shop light and my hands in this opening!
I'm trying to be patient here. This is a big job for a novice, but I can only imagine what the shop would charge!
