Has anyone tried one of these transmission mount inserts from revshift ?

If so, is it worth the $50, and do you need to remove the trans mount from the car to install it ?

also, any more noticeable vibrations ?

Thanks.

Do it!!

Yes please...I likey. Let us know how it goes.

I'm assuming that this will get rid of some of the flex in the drive-line and also help with the wheel-hop too,
the axles are great, but there is still a little more room for improvement.

I'll buy one shortly, getting motor mounts and other work taken care of first.

I ordered one this morning. If I come up with anything worth reporting, I will.

sounds good fuzzy thanks

Hey Fuzzy, how do you like them? How did you wind up doing the install? Did you have to take the OEM mount out, or is there a way to do it from under the car?

We were just discussing this on the LS1tech forum. I purchased and installed this insert and love it, although I have to warn you it was a serious pain in the ass to install. On my car the trans mount has collapsed a bit with time so trying to push the insert in past the outer ridges was a lot of work. The only way I finally got it in was to take the cross member off the transmission, put the cross member under the legs of the engine crane then hook the crane to the top of the mount and use the crane to pull it apart just enough to get the mount in. Even with the crane it still took 30 minutes with a pair of flat head screw drivers to work it's way in. The OEM rubber is really stiff and it takes a lot to pull it apart far enough for this to slip in.

With that said, once I got it in it made a HUGE difference to the feel and shifting of the car, It's like a whole new car. Over time the mounts compress causing the geometry of the linkages to be all jacked, with this insert it is solid and straight now, worth every penny and I am glad I made the purchase!!

Thanks man, great description. From what you're saying, it sounds like replacing the mount altogether may be easier-- what do you think?

 

[FuzzyLogic]

I have an idea regarding how to install this thing with only basic tools--I'll let you know how it works. I think the main complaint about the Creative Steel mount is that it's very, very hard and therefore transmits vibrations very easily. It's also expensive.

I just installed the insert and motor mounts. No need to remove the mount, takes 15 min or less.
-Get the exhaust pipes out of your way (removed the midpipes on my corsa).
-Put a jack under the back of the trans with a block of wood inbetween.
-Jack up the back of the trans until the mount hits its uptravel limiter.
-Lube up the insert
-Shove it in the gap in the mount (this will take some force. I got it started then bumped it in with a dead blow hammer)
-Drop jack
-Re-install midpipes
-Enjoy no extra vibes, less trans movement and a non-sunk trans mount

I am quite pleased with the whole package (motor and trans mounts)

I believe I can do that. Great instructions. I might try putting the mount insert in the freezer overnight too, like I did with the diff bushing.

I just ordered it and will definitely be putting it in the freezer overnight to help move the process along but I had the same idea jack up the tranny relieve some stress shove the mother f'er in there

How do the motor mounts feel in combination with the trans mount? Just curious about the vibes.

Edit: saw your post in the other thread. Might have to pick these up in that case if the vibes aren't bad. My stockers are shot and I feel a bit of a shake at idle and shutdown and get the loud bang between 1-2 shifts.

The creative steel mount is actually pretty soft. I'm pretty damn sure it's softer then the stock mount + insert combo. The creative steel transmission mounts have a bad rep because the first generation ones were way too stiff and everybody hated them. The current ones are perfect. Just more expensive than this option.

Are you insane? It's rubber. Putting it in the freezer is not going to help you--in fact, it's going to hurt you. Big time.

Great workaround! My transmission was not in the car when I put mine in and the mount was crushed almost completely flat.

I tried the exact same thing earlier with poor results. I think his transmission mount is softer / more worn than mine is (24k miles on my 06).

Isn't it a polyurethane; more of a plastic.


Anyways... Got mine on order

I have 65k on my 05. By no means am I saying it slid right in, but if you jack it up all the way to the stop, lube it, get the front lip/edge started into the mount then you can beat it in with a dead blow hammer. When you are putting it in watch the slot in the insert and make sure the edges aren't getting caught on the center post of the mount.
