1995 SL500 project car... 120K miles
Drove perfect for 2 weeks, all new fluids, filters, seals, etc. One day, started to flare up 3-4 , but only when hot. Parked for a week, started driving - cold, beautiful.
When warms up, flares, does not want to upshift. Gradually, flares got to all the gears on the warm car. Basically non-derivable now.
Changed fluid to Type F helped for a few days, but now back to the same flaring again... Cold car shifts fine, once warms up, useless, flare through all the gears, does not want to upshift. Bowden cable adjustment made no difference at all. Im assuming this is not electronically controlled transmission (other than the kick down solenoid)?
Any suggestions as to where to look/try next are greatly appreciated. If I can't get the transmission issue resolved without removing the actual transmission, reluctantly, I will have to part the car out (or sell it as is), which is a shame, quiet engine, AC works, pulls like a freight train!
P.S. Cold - shifts absolutely fine, first 10 min or so.. Gear changing time to P from any position is about 1 second, to D is instant. No indication that she is tired at all, but only when cold!
