The car has about 150K mi on it. I doesn't shift to 3 or 4th gear. I can't tell, but I can't go over about 30mph. The shifter has D,3,2 selections. It seems like it's stuck in 2nd gear, but when i move the lever down to 2, it downshifts.
I replaced the filter and fluid. the filter looked clogged, but the fluid was clean and I didn't see any metal shavings. At one time it failed to go in reverse, but that hasn't occurred again.
My questions are, 1)what is the probable cause. Is it repairable, 2) How hard is to take out and 3) I see some low cost Mercedes model around $1000(86-91), Which years/models use the same transmission, that I can swap.
Thanks,
Jerry
