there is NOT much information on these chips for the older BMWs, more info in the newer software downloads. The only info really pertaining to these are at from Dinan itself, which in my oppinion is kinda one sided. I would definetly want to try one after I get my chip if I still have transmission issues but other than that I cant get enough independant information to justify the cost.
You quote 200-250, I was readin more like 299. Cant find anything about anyone else making a trans chip, try it and let us know??
