1990 BMW 735il
I basically want to know what other BMW I can get a trans from....I was reciently told I had to get one from an exact model...but through much research I've learned that the 4hp22 is in so many other model cars....PLEASE HELP....I've been w/ out a car for 3 weeks!

Answer
The only thing I think will matter is if it has the eletric sport shift on the console.Measuring the trans mission as for the length to make sure the transmission is the same length and that it is a big block(3.5l)engine,if that is the same(like say a 5 series) your on the road again.
