Tranny **** Tubes 1993 atx question..Reverse prob..

[saint007]

Hi !
Just want to say that this is forum is absolutely brilliant..

Okay , I dropped my tranny oil pan and changed oil... I taked a picture and
its here

I have problem with reverse -- not enough power...
Then i compared it with picture , i founded that picture from forum..

I circled one **** tube ,it seems to be dropped down??Am i right??
And also i found that theres missing one support bar??
I think those are very important things to get more power to reverse gear..

Can somebody help me a bit ... Thanks

When Project89SHO did his tranny rebuild he had a problem with that tube. He was able to solve it. I'm sure that he will chime in on this one. That bracket in the second picture almost looks like a makeshift solution to the problem - because i've never seen it in my tranny. Looks like you've had a recent rebuild or the inside of your tranny is just for some reason amazingly clean.

The reverse apply tube is the shortest of the five tubes. It is the one at the lower right of the second photo and is hidden behind the filter in the first photo.

There are several versions of the retainer brackets around. Shown are two versions. One change was the filter retainer clip which also doubled as the reverse apply tube retainer.

The circled tube in the first photo is the rear **** tube. It is press-fit into a bushing in the rear planetary support. It does not have anything to do with reverse. Make certain it's secure and is not loose fo present loss of **** to the rear planetary and differential.

Inspect the reverse apply tube to make certain it is not loose. I had to pull mine out and sealed it with Locktite 272. 262 was recommended but wasn't available.

Is your 1st gear engagement positive and reliable at all times? Or does 1st gear and reverse work okay when cold but delay or slip once the fluid warms up?

If only reverse gear is affected and it is not temperature dependent, then there is a problem related only to the reverse clutch and its hydraulic circuit.

If both 1st and reverse are affected, then the infamous forward clutch piston is the likely reason.

yup that is the tube that pops out, that pic I recognize, thats is my lil brothers transmission I did for him, I had to make a brass insert to seal the tube, and the bracket you see is from Sonnax, its an afterarket piece
made to keep that tube installed, you have to buy the complete kit to get that one bracket. hope the info helps

I happen to have the Sonnax catalog. That bracket is available separately under part number 96806 and will hold the **** tube and the two forward lines in place. It does not hold the reverse tube (different bracket).
