Where can I have the TCU tested or rebuild?
My 1998 318i started having problems shifting between 3rd and 4th gears. My mechanic rebuild the transmission and the car still has the same problem. In the morning when the car is cold it will go thru the gears fine a couple on times and then just refuses to shift between 3rd and 4th gears. I took it to the dealer for diagnostic and they told me the transmission needs rebuilding. My mechanic looked at it again including checking the electrical components and everything was OK. He says it is the TCU. I purchased a TCU from eBay and the car does not want to shift in 1st gear. I have looking for a place to possibly check or rebuild the TCU.
