Deano 1 Report post Posted December 6, 2009 This car as a faulty trans...probably bad clutch pack from what Ive read. Question is will a 4hp22 from a 1990 E30 325i fit? E30 trans has a 3 bolt output flange and a 2 pin plug on the side. Thanks Quote Share this post Link to post Share on other sites
Silver Fox 43 Report post Posted December 6, 2009 No, the E34 has a M30 motor, the E30 is a M20, different bolt pattern amongst other things, output flange etc. Quote Share this post Link to post Share on other sites
Deano 1 Report post Posted December 6, 2009 No, the E34 has a M30 motor, the E30 is a M20, different bolt pattern amongst other things, output flange etc.I was hoping to swap the bell housing and it would fit. So the 530 will have a 4 bolt output flange? Could that be swapped.I have the good trans and can pick up the 530i for nicks Quote Share this post Link to post Share on other sites
Silver Fox 43 Report post Posted December 6, 2009 The 530 has a larger 3 bolt flange, I'm pretty sure the box is too different, but Brent or Marty will know. Quote Share this post Link to post Share on other sites

BMW ALIEN 0 Report post Posted December 7, 2009 Hi, Is it the 1990 530 V8 you are refering to? If so I have an autobox taken off an M60 engine. Was working well at the time, though it has done high k's (replaced with a manual conversion). Let me know if it could be of use. Grant W Quote Share this post Link to post Share on other sites
Silver Fox 43 Report post Posted December 7, 2009 1990 will still be the M30 engine I think Grant, M60 came in 1992. Quote Share this post Link to post Share on other sites
