No luck, with the late model trans on my truck I'm gonna have to notch my crossmember so my oil pan and stock manifolds will clear the crossmember under the engine, just curious if anyone else had ran into this issue when using a 03 or newer transmission
The transmission cases are all essentially the same.Originally Posted by 1991SSP
Interesting,, the only way I'm gonna get the clearance I need is to place the transmission back an inch or so
Using 1" setback mounts is normal to put the trans in stock location, do you mean you're going 1" back from the stock Trans location?
Yes, with the trans mount being in the stock location my engine is too far forward, I had to notch my transmission crossmember to allow it to slide back a inch or so, if not my oil pan was resting on the K member and my drivers side manifold did not have enough room to clear as well
Every 88-98 frame I've seen has multiple sets of holes to move the trans. crossmember front to back. Just set your engine mounts in the 1'' back position then mount your trans x-member to the closest set of holes, you may have to drill one or two new holes.

I believe low91 has got it right,especially the drilling of new holes which is no biggie.
