Looking for some reviews of the TTR solid upper engine mount and tranny bushings on SS/TC's. Since the TC already doesn't have much wheel hop, if any, I am wondering how much good this upgrade will do. I'm also curious how many TC owners have this upgrade. Thanks in advance.

 

I bought both, and have to say I am very very pleased. IDK how you don't have alot of wheel hop, but mine was unbearable. I got the TTR motor and trans bushings, and i can't MAKE it hop.

The motor mount: The vibrations aren't bad, I actually like them because I hate streetability, and it is my goal to kill it with fire. It was SOOOOO easy to put in, and looks good. I would say definitely do it.

The Trans bushings: PAIN IN THE ASSSSS to put in. They are technically for a SS/sc, but will work with a little modification. Basically, what I had to do was take them to the bench grinder, and grind one side's lip off, then i had to grind a bevel onto the same side (leaving the other side normal). Then, since i didn't have a press, I had to lube the utter crap out of it, and use a vise to push it in. This is DEFINITELY a 2 person job. We used a long board to sort of 'steer' the bushing into the mount, since if the top went in, the bottom popped out, and vice versa. All in all, it took about an hour to do both trans mounts. BUT... I think the benefits of the bushings outweigh the time taken to put them in. I have much less shifter play when i let off the gas, and the shifter feels a bit more direct. I wold say, only do this if you are pretty mechanically inclined, because it is a pretty intense install, and you will definitely mess up the stock bushings getting them out, so you can't just swap back to stock.

Hope this helps ya!

 

Thanks for your review! We have heard many SS/TC members state this about our mounts.

 

I have both, but I'm a sc. So I can't say how they work on a tc, but I can say they work very, very well on my car. They are definately good qualty, you won't be dissapointed.

 

That helps a lot. Great review. Thanks!

Aaron, any plans to modify the tranny bushings to make them easier to install in the TC?

 

Not at the current time, the "mold" cost is very expensive, and they do work on the SS/TC as stated, it just requires a bit more force...

 

I would bet that with a proper press and a bit of luck, it would be easier. I took pics of how I did it, but my camera tweaked out, and didnt process them all the way.

I guess a couple pics turned out...

Here is the stocker by the TTR (you guess which is which, lol):


And this is how I modified the trans mount:


This is half the pic of how we pressed them in

As you can see, there is a board going up. My buddy was pulling or pushing on the top of that as I turned the vice. This 'steered' the bushing in straight, like I said in the previous post.

 

Awesome. I'll have to check out the pics later tonight, my firewall at work is blocking!

 

I think they are just as tight on the ss/sc aswell. When I did these on my ss/sc I used heavy duty machine grease to lube them up and a 200,000 excavator press them in. On one we didn't put enough grease on and it ripped the bushing and I had to get another. I would have to say that getting the old bushing out is the hardest.

I have yet to install my TTR upper mount on my new SS/TC, it doesn't really go with the new car due to the TTR mount is silver and my new car is black.

 

Good to hear you guys like the TTR's, its about to be my first not-free mod.

FWIW... Installing older mount inserts on an MR2 sucks just like that too, and often people would put the bushing in the freezer over night and then put the mount in the oven (don't kill it! just on the warm setting!) and makes our lives a little easier anyway. Hit it with some silicone spray or grease too when pressing.

On the newer MR2 bushings they made them 2 piece, so you don't have to go through the drama. Might be an option down the road for TTR? Makes it like a 20 minute job on the MR2 now that they did that change. Hell maybe use a bandsaw and cut the thing in half yourself and then bevel the edges slightly.

Here is a picture of what I mean:

I have a hard time believing those would be as stiff as a single, whole bushing.

 

I can ASSURE you MR2 is about solid as it gets in the mount dept Its just front/rear transmission mounts not torsion/side/lateral/whatever you wanna call it. Its still a press job with a vice to get them in, I don't mean that they just flip in with no effort. Every mount insert maker has switched to that 2 half design now for that platform and i've never heard of any issues in my years of ownership. I mean basically you just dont want any front/rear slop and they solve that.

Also on the MR2 the mount that you slip it into surrounds it like so and secures it pretty well:

Sorry to always compare my Cobalt to MR2, its just the car I've been modding/playing with for many years now... so I try to share experiences and things we've figured out as a community.

 

Ah, i see how it works. It is a bit more tight than the Balt, so it seems.

 

Does anyone have a picture of the other end on the Cobalt?

I've not even had my car on a jack yet, I suck.
