Mercedes 190E Automatic TRANSMISSION problem

[RaF944]

Hey guys my brother is having a transmission problem with his 190E and here is what he said

"On my 1990 190E 2.6L Mercedes, I experienced lack of shifting so the
engine was reving at high RPM's. Sometimes it would shift sometimes it
wouldn't. I would have to put it in neutral and back in drive for it
to shift sometimes. A mechanic said I have an internal leak in my
automatic transmission. He said he took off the oil pan and was
to determine that. After putting some Lucas stop leak in the trans.
the car drove for about a month without problems. Now, the car
won't shift past 2nd gear. The fluid is leaking heavily
from the bottom. After trying to put 3 new qrts. in, it all drained
out the bottom. Does it need to be rebuilt or should someone else
look at it?

Sounds like you might just need to seal it up! Get it so it will hold fluid first, then see if it clears up....an auto trans will start to slip even if its "only" a quart low....replace the pan gasket, top it off, and see if that fixes it.....
