# Automatic trans downshifting problem.. broken trans mounts??

Posted by PaxMax (91 SE Automatic Trans with 155K miles) on July 03, 2002 at 06:06:59:

Hey guys,

I have been noticing an annoying problem with my
rebuilt tranny. My automatic transmission was rebuilt
2 years ago at 145k miles. The problem is that
when the car decelerates from "35" mph to "0" mph, the
car makes a loud and painful bang when shifting from
2nd to 1st gear. I see that rpm's go from 800 (gear 2)
jump to 1100 rpm (switch gear 1) then back to 800rpm again. (idle). This happens when I step on the breaks
to stop in city driving and happens when I let go of
the acelerator and let the car normally slow down.

I am hoping that changing my transmission fluid would
fix the problem.

My Nissan Diagnostic said that I have 2 broken
motor mounts and 2 broken transmission mounts.....
Is the above problem related to broken transmission
mounts? If so, how much would I need to fix it.

Thanks,
PaxMax
