Re: [MBZ] B2 diagnosis
Thanks! this and Jim's tip about the kickdown switch are great starting places. Anybody else got trans troubleshooting ideas? When/how do you pronounce the sucker dead?

Total B-2 piston (or band) failure results in NO forward motion and reverse is fine. If the piston is going to fail, it's rare that they don't fail suddenly (they don't go slowly over days or weeks). If it takes longer than 2 seconds from N to R, the reverse clutch pack is worn (first signs of serious transmission wear). That's entirely unrelated to B-2 piston or band problems.

Re: [MBZ] B2 diagnosis
Start with a Mobile 1 ATF fluid/filter change. That cured my CD which had a slipping trans until the speed was above 15-20mph. I'm a believer.

Re: [MBZ] B2 diagnosis
No, the symptom of a bad b2 piston is you shift into drive and it never goes into gear. If you have the shift into gear and it takes 3 sec then the tranny is probably just worn out.

Re: [MBZ] B2 diagnosis
ok, well the updated B2 is supposed to have a groove so that the shift/response time is shorter.

no, there are many things that could cause that. First of which would be the control pressure cable which connects to the throttle linkage.
