Ok, this is a weird one...I have a 86' 300SDL with 141K on it. When I bought it, the guy told me the tranny was rebuilt a fairly short time ago. Never trust that someone has done all proper general maintenance on a car...so I changed the tranny filter and fluid at 129K. However, before I did this, I noticed the tranny had a funny little slip to it.

When cold, the tranny shifts fine...you have your typical erratic shifts here and there from the throttle but thats normal with these trannys ive been told. (erratic meaning it shifts at weird RPMS but still shifts)

When this tranny gets warm though...it slips from 2 to 3. Not a terrible slip...but makes the engine RPMS go up a little before shifting. Its definately best described as a slip but only when warm and only from 2 to 3. I checked the fluid today...clear clear red and no funny smell (the smell of burning from overheating in the fluid).

What do you think this could be...Lucas Stop Slip didnt seem to remedy the situation.

Brian Carlton...I know them gears in yer head are turning, I could be more detailed if need be!
