I’m wondering if my 99 Bmw 528i transmission with a bad engine can be a potential doner for a 98 bmw 528i with a good engine bad transmission help so I jump on the purchase before it’s to late
Looking at Wikipedia, it appears there were two different automatic transmissions used in 1999. Depending on when your car was manufactured.
The two autos are the:
- GM 4L30E - Used up until 06/98 manufacturing date.
- GM 5L40E - Used from 07/98 to 03/00 manufacturing dates (inclusive).
There was only one standard shift tranny for either of the years, the S5D 250G.
If you have an automatic transmission and it falls before the 07/98 manufacturing date, you should be fine. If after that, then the two would most likely be incompatible. It looks as though, the standard version shouldn't have an issue.
