Poly Trans Mount?
Is there a poly trans mount available?
My 2011 5.7 is shakingshimmying/shuddering under braking (190,000 miles). We ran it on jackstands much to TCS's/ABS's chagrin and it still does it. We can't tell where it's coming from but the back of the trans is moving around alot. The mount is still in 1 piece but is a cheap part to replace.... I'd like to put a poly one in if I can but all I can seem to find is rubber?
O'Reilly doesn't stock one at all for RWD, only 4WD. RockAuto has a few different options. Advance shows the Anchor 3377 for $110 while rockauto has it for $45.
