I recently bought a 93 rx7 and the car needs new transmission mounts but i cannot seem to find any. Could someone please tell me where I could but them or even give me some links thank you!!!

 

intresting question

 

There are no tranny mount in a FD. We have PPF(Power Plant Frame) which is like a back bone that connect the tranny to the diff.

Also OP's motor mounts could be bad. This will cause lots of movement in the trans as well.

 

Chances are your PPF is cracked.

 

i made some motormounts out of some round aluminum stock 3inch

 

I could show you how to make 3 set of engine mounts made out of polyurethane for like $90. Then sell the other 2 set and make your money back + some.

 

when im driving its fine but when i let go of the gas cruising in like 2nd gear the tranny starts bouncing around in a way.
it sounds like a bad mount or bad u joints in a driveshaft.
But scince there are no mounts any body know what it could be.

 

Motor mounts and/or diff mounts. Pretty common.

 

Any clunking?

 

Interesting. I could use some new mounts especially while my motor is out & making my own would be a good time.

If you look for an old post made by Damian it has a "how-to" for this. The only thing that will make this an issue (but not impossible) are the earlier 93 mounts. There is one mount that has a hump where the actual mount goes so you have to carve that part of the polyurethane. The later ones are perfect because they don't have that hump.

Here is the how to

thanks. hopefully i'll get on this soon

 

hey im having the same problem, what fixed yours?
thanks

 

Chances are the PPF is cracked if there is alot of noise and the shifter bounces up and down. If not then the motor and diff mounts are worn. Install new poly diff mounts and a Banzai Diff Brace Differential (93+ RX-7)

If you want to add a trans mount then install our Banzai Crossmember Transmission Crossmember

 

That looks to be way sturdier, woll definitely look into get to getting one
Thanks

 

What is that plate attached to the PPF in the upper right corner? (not the brace you guys sell)

 

OEM heat shield

 

Top one is from over seas somewhere. Other one is from samberg performance

 

do you have the website for the overseas company that sellls that mount?

 

That second one would be better. It seems that it has a damper to reduce vibration/notice. That's the one thing I hated about the solid brace.

 

that second one would be the one from samberg performance isnt it?
ill go check those guys out

 

RX-7(FD3S) mission rigid mount

 

Search for Marcus Mazda on facebook. He has parts from Japan for sale.

 

i just sent him a PM on facebook.
