1981 AT hesitates when shifting into reverse

Anybody know how much oil is lost when you remove the kickdown solenoid? This is all that stopped me doing the adjustment last time I was in there.

joejoe I have found my '81 is slow to reverse when first started. If I let it warm for a minute or so it is ok. Not sure what issue is, If you find out post.
The rubber piston seal which applies the reverse band has lost its elasticity (hard), applied fluid will leak passed the seal, when the fluid heats up the seal becomes flexible, allowing the piston to apply the band.
Brad W My 82 does the same thing. It does not matter weather it is cold or not. Ther is a couple of second hesitation when I put it in gear till the time it engages.
Does anybody know where I can get a rebuild kit for the 3 speed? I have never sean one listed on PET. I have rebuilt some Chevy automatics so it can't be that hard.

4 Speeds were used in 1983; if you have a 3 Speed, minimal fluid will leak once you remove the KD solenoid,
You ready? 1 little 4 oz. bottle of Kendall Limited Slip Additive added directly to the tranny. Very stinky stuff, but works exceptionally within seconds. Will work for about 2 years and then 1 more bottle will be required. this stuff is so good it will give a car reverse back that hasn't had it at all in years in 2 seconds. Also great for cars that won't shift into overdrive etc. Note: This is not a selling tool, only for owners planning on keeping their cars for awhile without a major transmission expense. I will guarantee it will work, but it's only available at some Napa stores. You'll know if they sell it or not as soon as you walk in. The smell is overwhelming!
Try that and get back with me. Like I said.............guaranteed!

Totally disagree with you. Kendall Limited Slip Additive is nothing more than a friction modifier. No Coefficient of friction problem in these transmissions caused by transmission fluid.
Yes, a friction modifier can Prevents clutch and torque converter shudder, it also cleans valves, you can adhesive the same by a regular maintenance Schedule, change the fluid. The delay into reverse is purely mechanical.
In the A22 / 3speeds transmissions
There is an excessive amount of clearance between the reverse band and reverse drum, or a leaking B3 piston seal. Mechanical.
In pre 1990 A28 / 4speed transmissions,
Mercedes Benz had a B3 clutch problem, fictions material will peel off the B3 / reverse clutch plates, causing excessive clutch clearance, the delay. Mechanical.

I am overwelmed with the responses. I appreciate Steve Cattaneo expertise and extremly helpful pdf on the repair. As soon as I get some time , I'll do that. Thanks! Rennlist does rock!

Charley, I'll be honest, I don't like you. And I know you'll say you don't care either. You've never had anything good to say about me and always assume the worse. In fact, you assume the worse about alot of things, especially things you have absolutely no idea about.
For example, in regards to that beautiful old red '93 GTS of mine, now for sale by a dealer from Canada on Ebay for only $22K, you stated "black spoiler on a red GTS, hummmmmmm?" What an idiot, you didn't even know they offered a matte black finish spoiler as an option, and of course, once again assumed the worse in people.
I offered the advice of using the Kendall Limited Slip Additive for the original poster, not you, and the advice was offered with a note saying that it was intended for longtime owners looking for an inexpensive alternative to fixing their transmission cheaply vs. a full overhaul.
You jump on and quickly attack my character stating that you wonder how many 928's I've sold that I've actually used this on. Screw you Charley! I'm not that kind of person, nor would I ever sell anything that I had to use that product on to resell it. That was a personal attack of my character and slander at that! All of my cars are premium examples, nothing less!
You don't know me at all, so don't ever comment on me again. It would be merely conjecture and I'm sure in a negative way at that! Your an ***!
Todd Johnson
And P.S. 90% of the 928's I sell are 5 speeds anyway! But naturally, your looking for that 10%, I'm sure.................***! Your one of the reasons this site is suffering from negatavism and a lack of interest in newcomers.

Sorry if I was out of line, but some people might take that comment seriously.
No harm, no foul.

So, maybe a lil' better explanation from now on and maybe, just maybe, we can start dating again..............
