Prothane7-1604 Red Urethane 6 and 8 Cylinder Transmission Mount Kit

So much better than the Energy suspension transmission mount!! It is wider and stiffer, stock height with no need for a a pre-load plate. I I put it next to the energy one and with the pre-load plate the energy one was taller, without it is was shorter. This one is much easier to install since it has an Allen screw with a bolt that locks it in place. Just put the screw in with the bolt already on it, tighten it then tighten the bolt. Bought Energy version to replace my broken stock mount on a 98 z28. Immediately had drive-line vibration. Tried with and without pre-load plate, upgraded to an UMI torque arm relocation bracket, upgraded to an UMI adjustable torque arm and replaced the energy torque arm bushing with the prothane one supplied with that. Still had vibration. Bought this one and so far it's gone.

Purchased this unit for 99 Trans Am with the LS1 engine because I didnt want to spend that much on an OEM mount, it is aldo a bit dificult to locate a proper mount for these cars outside of the dealer. A side note for those looking, you can purchase a 93-97 LT1 rubber mounts from your local parts store and bolt it up to your LS1 powered car. Now back to the Poly mount. It installs in a few minutes and comes with the hardware you need to do so. You will notice a bit more driveline vibrations in the seat of your pants and on the shifter but thats expected since it is a poly mount. I have put over 3,000 miles on the car since installing the mount and have gotten used to the vibration (which is very slight). Personally I think if you are going to complain about small vibrations and harsh ride in an F-body, then you have bigger problems. Buy the mount, and use the money you saved for something else.

Installed this in my 91 Trans Am. 5.7 with 700R4 transmission. Works just fine, you may notice a little more engine/transmission noise since it is more solid than a stock rubber mount. Installed this at the same time as an ES Poly Torque arm mount.I took off 1 star because I had to enlarge the slot slightly (widen) in the transmission crossmember. The included stud is a hair to wide to fit through. Nothing 10 seconds with a grinder or dremel wheel can't take care of.

Excellent I'm sooo happy I found the causes of my vibrations from 45 to 65 mph. Old mount was torn in half!!!! U joints had 25% missing from one stud under a cap. Huge clunk when put in reverse but i was too dumb to remember what that meant. But NOW my 2005 chevy express 3500 6L with 700,000 miles will RIDE and PLUMB again!!!!!!! THANK YOU AMAZON!!!!!! Especially for the 1-day shipping, I got it in less than 24 hours. You gained my loyalty today. I'M GRATEFUL!!!! Your plumber TRU!

I had no idea how sloppy my stock YJ (Dana300 swapped) trans mount was till I replaced it with this. Though a smaller width unit, it is much stiffer. Stock mount had no visual tears or damage but I could move the rubber by hand. The transmission and transfercase used to move under load. Not anymore This part was an exact fit.

Product worked just as intended. But buyer beware, if you don't want to feel every little vibration in your drive train stick with rubber. This mount did make a big difference in stiffness, shifts felt harder and the car felt more responsive. But my T\A felt like it was goin to rattle apart.

For the V6 slight modification to bracket is required for this to fit otherwise product works well.

Well I love it I have a lot of vibration already and I destroy stock mounts every few months but put this on and after it settled in and I tested it out feels great no bouncy bouncy Tranny anymore it’s great
