My transmission (722.6 and late 1998 build) had a problem (74k miles)
where I noticed slippage/(difficulty engaging) starting from a stop
particulary heading up an incline (even modest ones and I was in the
"S" mode). When I slowed to a stop entering my garage and my rear
wheels came to rest just before the concrete edge or "lip", I had to
really crank up the rpm just to get over it to move forward. Needless
to say, I was "somewhat" concerned that the tranny would engage at the
wrong moment and my car just might end up in the family room.
I took it to my trusted indenpendent shop who sublet the job to
another shop whose $10,000 MB diagnostic machine spat out "electrical
relay problem" (this was relayed to me by the first shop).
A day later, the repair bill showed that they repaired the bad
"electrical plate" and replaced oil (8) + filter + gasket for $730.
Transmission oil was not bad and didn't show abuse. I am happy to
report that the car regained the sure touch starting from stops.
Question for the gurus, any idea what was replaced? I thought plates
were mechanical items and that only the electrical stuff like the
often mentioned valves or sensors generated fault codes. As I would
like to keep the car for a long time, would I have been better off
with transmission replacement (the ones with steel needle bearings)
and take the BIG hit now instead of many small ones in the future?
