Help Fast Please- Trans Mount Problem
I recently bought a Prothane Urethane trans mount for my TH-400. I just installed the matching motor mounts today after quite a wrestling match. The problem is- in comparing the height of the stock trans mount, the Prothane mount is 1/4-3/8" taller. I've already confirmed that I have the right part # for my application, so that's not the issue. The height difference concerns me since it will raise the rear of the trans by that amount, thereby possibly having an effect on driveshaft angle.
I called Summit & the guy said that the Prothane trans mounts in late model Camaros are also slightly taller than stock & have been causing vibrations in those cars. So, the big question is-
Have any of you guys used this mount & if so have you had any problems? I pretty much need to know by Sunday morning because I need to have the car together by end of day & should be able to get a stock mount at a local store.
If you don't have any direct experience I'd still be interested in your opinions. THANKS.

If it were me, I would go with what fits better.
There's no way you could "grind down" the tranny mount? Excuse my ignorance, but I have never looked at a tranny mount up close and personal...
Either way, can't wait for you to get your bad boy back on the road, Les. It should be a blast.

I would get a stock rubber mount and use it. Not only will your driveshaft angle be incorrect with the taller mount, but the fan will be lower in the shroud as well, which could cause some interference problems.

Les, 3/8 inch is not much differance, don't worry over it, loosen the rear bolts a bit, install the engine mounts, then tighten everything up....go have fun....

:iagree: 3/8 or 1/4 difference shuldnt hurt anything. heck, the old mount could be worn or deformed causing the difference between the two. ive worked with 4x4's that get much bigger shaft angle changes. 3/8" is nothin.
