trans hitting floorpan

[extreme gmc]

my trans shifts hard enough to make the tailshaft of it hit the floor of my truck, my question is how do i go about making the hump bigger or otherwise fixing my clearance issues. i got the jtr 'shaft alignment kit in and i really do not want to take it out. would urethane motor mounts along with the urethan trans mount i got solve my problem?

The rubber mount could be trimmed down some.

Mine shifts hard. It will lose the back end when it hits second and I have never had it hit the floor. I think maybe your rubber trans mount is bad, or engine mount. A lot of times oil can soak into the rubber and it weakens it.

i already have a urethane trans mount...

[extreme gmc]

cannot be trined either because of the way it is designed. trans mounts to one side and the xmember mounts to the other. i have thought about trimming the spacer but i could only trim about a quarter inch off of it and that probally would not make any difference...

sounds to me like a broken mount. that is the only way that it would hit the back. check all of your motor and trans mounts.
