Tranny shudder question

[mk8mx5]

Has anybody tried Instant Shudder Fixx by Dr. Tranny? I already changed the fluid with Mercon V and it was OK for a while but the problem came back.

Yeah, it tried it. It worked for awhile then the shutter came back. The permanent fix was to change the 1-2 accumulator piston and springs. If you haven't done it, look for TSB 97-11.

Good luck.

I just put some limited slip additive (the stuff that goes in traction lock/posi rears) in my trans and the shudder went away (so far).

Already did the 1-2 accumulator spring (leaving out the bottom one) a year ago.
