If I want to put a motor plate on the front of my malibu motor is it necessary a use a mid plate also? If a mid plate is used do you still use a mount on the back of the trans? Thanks - Steve

^^^^^^^^^^^^^^^^ There is your set up, if you put a solid trans mount in it, it will break the case, you can just let the trans mount rest against without bolting it also.

Thanks guys. I know I couldn't solid mount the trans. I wasn't sure about the mid plate. - Steve

This is in direct conflict to what my chassis guy told me.
Front mtr plate, mid plate = solid trans-mount.......... otherwise you'll break the case with a flexible trans mount. :confused:

(he's built plenty of chassis' too)

Well, I'll have to disagree with your chassis guy then.

it may also depend on the type of car and chassis. A full tube chassis car may be stiffer than most stock chassis door cars and may be able to get away with a solid trans mount. But most stock chassis door cars have some degree of chassis flex/twist and such situations require a rubber/urethane trans mount.

Think about it, if the chassis flexes or twists and the trans is solid mounted, what's gonna move/break first?

I agree there is no harm to having a good urethane tranny mount.

i know a guy who had a super gas doorcar and he broke several tranny,s , it was solid mounted at the trans , he had motor plate and a mid plate but now lateral mounts and the motor and tranny where moving front to back breaking the housing , he installed them and the problem went away .

and with today's generation of 25.2 and 25.3 cars i,m sure there's little to no flex when compared to stuff from yrs back , not to mention lots of guys running full SFI tranny bell housings and cases and they are a shitload stronger then the factory stuff .

(I can't make heads or tails out of the above ^^^.)
Is this a yes or no?

I'm going to solicit for Gilsbach's expert opinion...............stay tuned.

My Malibu has a front plate, lateral limiters, NO mid plate, and a rubber trans mount. No problems here. 3450# 9.50's at 140.

With front and mid plates there is nothing to be gained by a solid trans mount, its not like you want the case to be a stressed member, it will just distort it no matter how stiff the car is, it will just be less but all cars flex some just less, its not like the trans is going to flip over,,,,OH WAIT, THERE IS KEVIN CAPLOCKS TRANS!
