Is it time for a new automatic gearbox ?

[greffel]

Hey
There was no spring and I managed the keep the seals in place.
The gear box feels like it's in good condition. the only thing so far is that I was expecting a valve body with the letter "C" but is was i "A"

The vale body in my broken transmission was "B" and the new one I bought was "B"

Good job, I hope you've finally cured your transmission woes, Did you find that your shift flares are now gone also?

On Saturday we will know if the shift flare is gone
But with a completely "new" gearbox it must be impossible to inherit those problems.

Last time we talked was about my bewel gear.....it still work perfekt after new bearings

In the ATSG manual they mention that the rev C valve body is identical to the no ID (oldest rev) valve body except for differences to some spring calibrations, the valve body castings, separator plates and gaskets are identical. The rev A and rev B valve bodies are the same in terms of castings, plates and gaskets with some spring calibration differences.
I think what's more important than the valve body revisions is whether the valve body is worn or not and if the solenoids are sticking, or not. Keep the newer valve body you have if you can in case there's any problems with the R valve body.
Because you previously has a 3-4 shift problem you might want to look at the transmission you pulled out of the car, I suspect you'll find some badly worn 4-5 clutch friction plates. If you do find an obvious problem like badly worn frictions you'll know the valve body likely wasn't causing the problem.

Success !!
Not to bad for someone working behind a desk =)

First test drive it was shifting a little bit hard, I guess the old adaptation was completely different.
The I did the oil counter reset, adaptation reset and relearn
Shifts so fast and so smooth And no flare from 3-4 !!!
Happy

I will post back here when I get the old gear box up on the work bench. Something strange is going on with the 4-5 assembly

Congrats!

That's great news, nice work, it's so good to hear all your hard work paid off and now you have a transmission that shifts well. Will be interested to hear what you find with the original transmission.

Here's something from another post and by volvolugnut, it says it all...

"Many a time while wrenching I learned too late I should have stopped work before I broke something.
Hang in there. This is doable.
The satisfaction of a job is directly proportional to the difficulty."

I think the most important single piece in any transmission rebuild is a new valve body...

Hello again.
First of the "new" gearbox is still working just fine, as an extra bonus the transmission swap also cured my problem with long crank times. Sometimes the car would take extra long time to start.
But that problem seems to be gone also

I'm now thinking of do a "light" rebuild of the old transmission and sell .


First off, I hade to use a puller to be able to get the drum of the shaft.


With the drum of I inspected everything and found this marks!!! Probably the cause why I had to use a puller ...

Now to the really good stuff
Heat mark is never a good sign I guess ....

Removing the snap ring and a completely destroyed clutch pack was found ....
Not a single bit of friction material and the metal rings is not in the best shape.
