    Well I have asked many questions about this problem i have been having.(thank you all for the responses) I belive i have narrowed it down to motor mounts. When loaded heavy and shifting or pulling out from a stop it feels like the trans is gonna come through the floor lol... I can deffinatly feel the shifter moving when applying throttle. Especialy when theres lots of torque like when crawing up hill in low gear it will feel jumpy and lots of movement in the shifter.. Sound like motor mounts? T800 with a n14 460e

    Jake brake thats your problem i had a t 800 for 6 years replaced mine 4 times , mine had a flat design with angled end with one bolt in the center when mine would get bad the gear shifter would hit me in the leg when going in a low gear loaded using the jake . The kw replacements r not that great but atro makes a good aftermarket i use their torque rod bushings last a long time they make the motor mount out of polyurathane and steel hopes this helps!

    grump - Did you replace your own mounts? How bad of a job was it to replace them? Any tips. I have a new pair waiting to go in my T6. I am going to do it while switching my trans. Sounds like you had the same kind of mounts I have. Kind of a \_____/ shape with a hole in the center. They each come with a washer too.

    Yes i did replace them myself all i did was take the bolt out the cat had a flat pad on the block by the mount used blocks of wood with good bottle jack lift the engine one side at a time high enough to slip out the old n in with the new . i dont like the kw mounts they suck and dont last long thats why i would go with the poly ones that atro makes.
