what a long, strange trip it's been for sure!!

hey bill +1 on that! I guess as long as its running by sat so I can wrap up the pca AX series I'll be happy. if I miss 1 more event (missed 3 cause of this mess), I'm done for the season. (I have to make at least 50%of them to trophy). course it'd be easier/cheaper if I just bought my own darn trophy hahaha

hey brian amazingly, no hard parts have ever failed or indicated any abuse. I think the trans design/application is basicly fine/ within limits for the most part.

it's really just been my own stupidity - taking it to the wrong shop (R&S) that mis-diagnosed the original issue (a commonly stuck valve), putting up w/subsequent R&S induced messes, then a servo failure (should have been replaced w/the upgraded unit/another R&S screwup), cleaning up another R&S mess (bad breather hose), and now back to solving the original issue cause it apparently re-emerged for whatever reason (TBD if that's really it).

in some respects having ted go through the whole thing might be a prudent choice, given the R&S track record. I can't count on being stranded near a bar everytime

I think the moral is: ya gets what ya deserve for taking it to jokers. the upside is that I'm discovering and getting all the latest benzo updates and goodies so it'll prolly last longer than the rest of the car by the time this is over

- and maybe someone will benefit from this by reading it BEFORE they take their car to a 3 stooges trans shop

iirc, R&R should be about $700-$900 depending on who does it. 10 hrs in the shop manual I think.

ted charges about $2k depending on what needs replacing beyond the standard stuff he does automatically (includes upgrades).

not sure on the plate stuff. I'd guess it's worth checking prior to re-installation as is the torque converter. (figure about $275 to do a custom TC OH while it's out).

I suspect checking the TT anytime one is in the area is always a good idea/very easy to do if the trans is out anyway. mine is the OB style that has a circlip that holds the tube from sliding too much/alledgedly. later MY's could be an issue I suspect - and yours really should be checked given your "tweaks".

I'm going to get my pinch bolt reset/checked right after this is done cause I want to insure R&S didn't hose it up. I feel like I should sterilize or replace everything they might have touched.

Hang in there Rob, not unusual for it to take 3x as long to correct someone else's mistakes over just getting it right the first time.

For everyone's reference, here is the updated filter. It is from the 90-95 722.5 MB tranny, part # 68010C, the stocker for our trannies is the 68010A on the left:



Post a pic of the updated pan and reservoir when you get a chance, sounds very cool.

very good info adam!

dont' forget the updated servo either! might be good info for your trans thread. there were 4 versions. the 3rd has a teflon ring around it, the 4th also had a different piston and requires a different internal seal (easy to R&R if trans is out and apart). not sure of pn's... my pics suck, but I'll see if I can do something decent when I go back.

I'll definitely post any updates/upgrades on the rebuild thread. I hadn't heard about the reservoir/pan one, so I'm definitely interested in that one. Please post or email any more upgrades that you come across, I'll include them in the rebuild thread.
Regarding the servo upgrade, is that the same as the B2 piston upgrade?
If it is, I think I have the upgraded version.




The pics I've seen in the WSM show the piston with a flat face, mine has the "spokes" and the "teflon ring" you mention on the third version. Any chance of getting a part no. for version 4?

Thanks Rob.

I'll try to get PN's... yep, looks like the rascal in the above photo. they break at the spokes on the early versions cause the outer ring gets stuck sometimes. hence the teflon ring on outside for 3rd and 4th gen versions.

iirc there are a couple of oddball but key parts to replace on the internals to make it last too... I'll get details tomorrow when I pick it up.. ted is pretty cool about divulging general info, but I'm sure there is a lot more to it that he just takes for granted cause it's "obvious". prolly a good list to ask anyone contemplating using anyone else for a rebuild though.

ps - looks like ted called it right again. just a stuck valve. it shifted perfectly on the rack test and was dry! on the road test it lit up the tires easily so it's hooking up well (internally), but then it started leaking like crazy from the left side.

apparently my dear buddies at R&S didn't reseal any of the friggin plugs there and under load they can leak from 4-3 downshift shock. they kinda act like little fluid shock absorbers and take a pretty good hit sometimes. argh..

but ted will get'er done tonight - and in time for my sat night ax yeehaa!!

928SS

friggin R&S tards actually used silicone on the OUTSIDE in an attempt to reseal it!!! amazing.

was still blowing oil out the top vent for the AX on sat. prolly cause an internal seal must be hosed up too. almost got black flagged / caught. managed to get a finish on the books though

but enough is enough... took it back for a complete OH w/ted yesterday - gonna get this done right. ted quoted btween 1800-2k and a 3 day turnaround. should be done next week.

seems R&S also totally screwed up my rear alignment when they took the rear end out. friggin tards. guess I'll get to do that again too. at least it's in good hands now

Sounds like you found someone you can trust finally. Will you have him adjust (something - I don't know autos very well) it so it shifts differently?

928SS

hey b

should shift at about redline in each gear. used to anyway. steve c did an amg valve kit to make it shift quicker and get 1st gear starts which it seemed to do nicely when it did run. also have the kickdown bypass so it'll hold a gear like a stick too. that always worked ok, should again.

the other new parts just make it more reliable, help it shift more positively.

the TC change was supposed to take it to 1800 brake stall but I think Edge got carried away and dropped it back to 1400. they'll get it back tomorrow. there are 3 TC's availabile for this trans:
1350/1800/2200 according to ted. it was originally a 1350, then I had it shimmed to 2200. but that's a crappy way to increase stall as it makes things sloppy feeling apparently and 2200 made it come off the line like a wild bull w/the stroker behind it. great for burnouts, but a bit touchy on the street in front of johnny law or on a timed run launch. 1800 should lockup a bit earlier on the torque curve so I can minimize un-intentional wheel spin a bit, but not bog down like it did at 1350. supposed to help 0-60 times too.

by doing it w/impeller angles and clearances it's supposed to give a more positive feel like a stick, which it did nicely after the last rebuild. throttle response felt much tighter in general. just had too low a stall for my tastes. I think we'll get it dialed in very nicely this time.

928SS

Final Update: IT LIVES! ted did an excellent job for an insane price. no leaks. full power in all gears, nice aggressive downshifting and holds all gears to redline like a clock.

he had to replace the case, both planetary sets, drum, bunch of other stuff. he installed extra clutches to help w/the extra power, used a heavy duty drum, and the other stuff mentioned earlier. ran $2150, plus 750 R&R from Ole next door. had to realign the rear, only ran $100.00 and handles fine.

FWIW, the shop manuals clearly state if the car fails to move in any gear, it's either the valve body, govener, torque converter or pump. if there's pressure, it's the VB for sure. that's all it ever was, no need to ever pull the trans - till R&S began tinkering and fubared the whole thing up. hope this helps someone else

course, the AC quit on the way home... argh... gotta love the 928.

It's always something, isn't it? These cars can be harsh mistresses...

damn what a story...Makes my wallet hurt. My whole car was only 2k bones. Super glad you found a good shop and got her done right.

928 intl had some screaming deals on used LSD's for a while...
