Auto trans hard shifting

[brandonclum]

Hey guys quick question my fwd auto 1g turbo dsm is shifting really hard when being put in reverse and then into drive it does it weather its warmed up or not its really violent its shifts going down the road just fine but when i go to put it into reverse it does it again and again any thoughts? O I do have a aftermarket tranny cooler on there dont know if that makes a difference or not but ya

I noticed mine would shift hard from park to reverse when it was low on fluid.

I have put the recomended qts in there it was completely empty due to the trans being taken out when I rebuilt the motor so if I remembered right i put in the 7 or 8 qts that it needed i think 7

It will also do that if your rpm's are higher above stock due to higher vacuum/idle. Check fluid level too.

whats the status on your mounts? my 2g did that until I changed the roll stoppers and it stopped after that.

Sounds to me like the polyurethane mounts are causing it.
