Hey Guy's,
I could really use some help from you MBZ Techs.

I have been reading and looking for answers and am very confused.
I was just going to replace my transmission, but figured if I could save that expense, the money could be used for other "goodies" for the car. Here's my problem, I had my trans serviced about 4k ago, filter, fluid, and modulator. I took it on about a 100mi ride on the turnpike, got off and when i came up to a light it started to slip in first gear, but only if i got into the pedal, if i slowly accelerate it is fine and shifts thru the rest of the gears fine.
Does this sound like it is shot? Every place i have called says it needs a rebuild, but im not convinced yet given what i've read in the forums. Maybe the B-1 piston?, modulator adjustment?, other type of adjustment?
Slips only in 1st, but always shifts fine thru the rest of the gears.

Please help before i spend 1500.00 on something that could have been fixed.
Thanks,

Ed;
If it only slips in first gear it is probably related to B-2 or the valve body.
Remove the rear piston cover on the right side back of the trans.(to do this push the cover in and pry out the lock ring) pull out the piston and see if it has cracked or broken.
If it is broken just replace it with a new one,if not reinstall it making sure the thrust pin is installed correctly,then consider a used or recond. trans.

Thanks for the reply Mike.
I'll try to look at it this weekend.
