I purchased my BMW 2002 new in 1974. After 135,000 miles on the odometer, I started completely rebuilding my 2002 in the mid-1990s, and in 2021 it was finally drivable.
I had the engine completely rebuilt. The clutch, throw out bearing, Guibo, universal and center bearing are all new. The driveshaft is rebuilt and balanced and the diff has been rebuilt.
But on my original 4 speed transmission, I only replaced the seals. The transmission shifts smoothly in and out of all 4 gears and reverse and I am using 2.1 pints of Royal Purple HPS 5w30.
I don't remember any noises when I pulled the car apart 25 years ago in the mid 1990s, but I now have the following concerns after 2,220 miles since reinstalling the transmission and getting the car back on the road in 2021.
1. I get a whine in first gear when accelerating and a much louder whine when deaccelerating when in first gear. This seems to come from the front of the transmission. No whining in any of the other gears.
2. I get a slight rattle in all 4 gears, which seems to come from under the shifter. It is not bad, but annoying.
Any suggestions?
1. Do I need a trans rebuild?
2. Are parts still available for the original 4 speed transmission?
3. What price should I expect to pay to have the trans pulled and rebuilt?
I live near San Diego, so any suggestions on shops would be appreciated.
