Hi folks,

My 1990 E34, 535i w/130k miles, sometimes feels quite gutless off the line. I noticed in the bentley manual that the transmission stall speed should be between 2100 and 2300. I checked my car, and I'm at 1600 RPMs (barely).

I am at 5000 ft altitude and I do have significant miles, both facts would drop the stall speed a few hundred RPMs. But 1600 seems way too low. The engine lopes a bit at idle, but it pulls as smooth and as strong as I'd expect it to even at low RPMs (although I don't have any other BMW to compare with).

What would cause such a low stall speed, and could a transmission shop do anything to adjust or fix it? Would a fluid replacement make any difference? It needs that anyway.
