Subframe trimming for tranny installs

Has anyone slightly trimmed the subframe corner where the tranny likes to get hung up on during installs?

Seems to me trimming this 1/2 lip in the trouble area would make install a lot easier.

I just take the steering column off the rack from inside the car, and then the subframe moves out of the way nicely..

I know exactly what you are talking about and all it would take is just a smidge. I'd just be hesitant to start grinding away at the subframe although Ive already cut into mine in the past thanks to seized LCA bolts.

If you have the cash the best option would be to pick up one of those trick lightweight subframes. Not only would you shed weight there would be some much more room in there and would make dropping the trans a breeze.

I've thought about that but was unsure of the amount of work involved.

How do you avoid alignment issues this way?

Also if the column is all you're disconnecting, how far does the subframe actually move?

Well, we are only talking about grinding about 2-3 inches along that edge, I wouldn't think that would drastically affect subframe strength.

Just lowering the sub-frame a bit has always worked great for me.

no alignment issues, its a splined shaft. Granted, you should get an alignment done whenever you drop the subframe. Just make sure the steering wheel is locked centered. It then moves as far as the power steering lines allow it to, which is quite a bit..

Sweet, any adverse affects?

Did it make it much easier to get it installed?
