I recently realized my transmission on my '97 GTP was basically done after 204,000 miles. I was going to repair it but found another 4t65e-HD with 78,000 miles and bought it. The problem is that it is from an '08 Chevy Impala SS. On my car the starter is mounted to the block and on the new transmission the housing doesn't have the bulge to fit the starter like the old one. Instead it has a place to mount the starter on the housing just on the upper side of the block. I'm wondering if anyone has ran into this and knows if a starter can fit between the block and headers. Also, I am concerned about problems from heat.
