Manual Transmission Mount Just Snapped

[Halogen]

Act of God ?

probably not, but it's parked and I'm not driving it !! Been arranging for parts and repair labor so I can get it fixed asap.

Anyone want to chime in on my bad luck ? Things I should watch out for ? Cause of the failure ? Future concerns or repairs ( bent bolts in other areas, engine mounts, transmission, clutch ) ?

Please help, thanks

Just curious year/mileage on the car?

Did you drive it aggressively? Our cars are notorious for bad mounts though.

Where did it break? On the top plate or the 'foot'? The top plate has a rubber bushing with a bolt that goes through to the transmission housing. It is possible that the bolt broke, or the bushing tore. Make sure you buy a new bolt when you install the new mount. Also, you might want to consider upgrading to a quality rear mm to reduce stress on the other mounts. You might want to consider an aftermarket tranny mount; but be aware that they are fairly harsh in terms of nvh.

The tranny mount broke...really? Out of all of our mounts I thought the tranny one was pretty hardy stock but I guess not? If you're looking for something cheap, I have my OEM Tranny Mount that's in fine working condition that I could sell you and even help you install if you wanted to learn how to do it yourself. Doing a RMM upgrade might be worthwhile as well but it'll likely take a while to get the part(s) in. The RMM is the easiest of the mounts to change although you have to do it from underneath the car so it can be a bit of a hassle.

As 'Donutz' said, there will be increased NVH when upgrading to aftermarket mounts. Both him and I have all of our mounts done so if you want, I'm sure you can check out either of our vehicles to get an idea of it.

The car is just nearing 105,000km and is 5 years old, so 2005...

As for the location of the break and cause, well the mechanics today seemed to believe it was due to improper installation after a recent clutch replacement, bolts being too loose or improperly torqued.

Take a look for yourself











I had the new part installed by 3:30 pm and was back on the road 205$ poorer, but glad I was able to land some fair deals.

[Donutz]

Wow, that is definitely broken! That's the 'foot' I was referring to.

[taz4432]

That's not even technically the transmission mount, but it's crazy that you managed to snap that and $205 for the part and installation isn't the end of the world although it's quite an easy fix to do even in a driveway.

I'm glad I do just about everything myself nowadays. Money saved + experience gained + new things learned = awesome.

Holy crap. Thats nuts. Guess its pretty easy to visually find out when a mount snaps lol.
