This can be installed with the trans in the car on the 2WD models. By removing the cross member under the transmission, you should be able to nose down the trans housing enough to pull the trans carrier mount bolt out at an angle. This will free up the trans carrier, allowing access to the bushing from both sides. Upon reassembly, slide the bolt into the bushing from the opposite side, as there is sufficient clearance from this side.

Please let me know if I can help with anything else. You can contact me directly at [email protected]

Interesting comment on 2wd. We fought that bolt when dropping my motor a few weeks ago. Got it out after a wrestling match.

Yes, another member here was also able to remove that bolt with the trans in the car as well. It is a tight fit, and care needs to be taken, but it's definitely possible. And it definitely beats having to drop the transmission!

I think this is going to be dictated by the motor mounts you're running. I can see standard motor mounts yielding enough to drop the trans nose far enough. I can see Wevo mounts struggling at having enough yield to pull this off. There just isn't much bushing material to flex. You don't want to force / bend the the inherently weak carrier.

Obviously this is to be tried at your own risk, as I have not installed the Inserts on a semi-solid equipped 2WD 964/993 so am unable to confirm this, but perhaps the semi-solid engine mounts can be loosened slightly (at the studs) to allow for more play btwn the mount studs and carrier.

ok kids, I spent some more time with the car this saturday.

bottom line, if one only knew a 911 from stories, they would get in a car with this tranny insert, wevo motor mounts, and a golden rod and go..."yup, this is how a 911 should shift".

It just feels crisp with very little slop. how it should be.

My recommendations:

1. wevos or rs mounts...just do them
2. golden rod
3. tranny insert
4. short shifter (optional)

really changes the car for less than $650

Quad, can all those be done to normally aspirated NB 993? I ask b/c don't you have a turbo model?

yes, all these can be done on an NA. There is a slight concern over engine carrier weakness with wevos, but I think if you go with the softer black pillows, you'll likely be fine.

I've done 3 of 4 of these so I guess I'm on the right track!

Not being the mechanical type, do we have a ballpark cost on how much an Indy would charge to install this? I've got WEVO Blacks so would they likely need to drop the trans nose or given their skills/tools be less likely to need to do that?

Sorry for the silly questions, but I'm intrigued by this product given the improvements I've seen with the other 3 upgrades....

not sure on the NA cars, but I can't imagine it would take a skilled indy more than 2 or 3 hours to do this. It stings a bit if its not DIY-able for the average person.

I know this product is quality but at $130 bucks it's a bit much. For about $30 bucks I got liquid urethane and poured my ownName:  image.jpg

That's one way to do it. Clever. Only downside is it is not reversible, but most people probably wouldn't care or notice.

Filling your transmission mount with liquid urethane, or similar, will stiffen your mount, but there are several drawbacks to that approach:

1. It lacks the sidewalls inherent to the Trans Mount Insert design, so it won't effectively limit lateral engine/trans movement
2. It takes several days to fully cure
3. Chances are, the urethane won't be the proper hardness rating
4. It is permanent, so if you want to return your car to stock form (to sell it, for example), it will cost you over $200 to purchase a new transmission mount

I understand it's not reversible, but I'm NEVER selling the car :-) Here's a pic with in the mount.Name:  Tranny mount w spacers.jpg
