Tranny Mount Disected and Fixed

[Laloosh]

Its ghetto but it will have to work till cpe completes their tranny mount!
So my car is down, just sitting in my garage waiting on parts. Ecu is maryland, wheels are somewhere in the united states on a truck, catless tbe is in maryland....so im stuck without a car and extremly bored.

After clay baring and waxing it lol, i decided to compltely remove the tranny mount to see just how bad the damage is.....O M F G...the thing was holding by threads.

There is a cheap insert type thing on the bottom of the mount facing the ground...well that insert was dangling as it was completly ripped out of the mount. The only thing preventing it from falling out was the tranny bolt. There is a good 2 inches of play in the mount without that insert...explains why i wheelhoped and my engine does backflips with the 2 step/shift/launcing...

After figuring out and matching up the tear marks i decided to epoxy and jb weld the fucken thing in there and it came out good. Ghetto, but i bet it does the trick untill a real solution is available. Cmon cpe!! lol

Here are some pics from my bordem.

Shit looks factory! Good job! You are the JB Weld king lately! Send it to Mazda... LaLoosh TSB

[Laloosh]

it looks liek dog shit but i tugged on my motor as hard as i could and it didnt fucken budge!!! Before if i leaned on it it would move lol.

Like i said, temp solution so i can rip it up at the track till cpe makes their tranny mount.

[Meder]

Those same holes are there on my new speed, my old speed, and all the other tranny mounts i have seen. One of yours does seem like it ripped more.


DO other people not have these holes/rips on the side of the mount to begin with? Could it b e possible that they are just there to release some of the stress of the mount and allow for a smoother overall ride? I admit, I do not know what i am talking about, but all the mounts I have seen look like that. Anyone else remove their mount and not see these holes on the side of the mount?

[Haltech]

loosh abuses his car! Thats why! Im sure mine isnt looking all that hot. I think ill get down there and check mine next.

chris, i see where you put the JBW, but where is the epoxy at?

[Laloosh]

The holes are there from the factory, however mine was torn up a lil more then stock. The problem lies with the insert, mine wasnt instered as it tore itself out hence the reason i had so much engine movement.

The epoxy is in all the gaps, once that cured the jbweld was put on top to fill remaining holes. Whats not shown is the lovly duct tape job that will prevent any of it from falling out.

[Meder]

i understand, we need these side mounts pretty soon it looks like

[JimmyMac]

Okay, let me understand this mount. So please bare with me. The black outter housing is what I'll call the "frame". In the middle of the frame is an aluminum block that is supported by a rubber bushing on the frame. It basically floats within the frame. Around that is a rubber insert that somewhat keeps the aluminum block centered. And aborbs vibes. Is this correct so far? So all that is really supporting the tranny/engine is the rubber bushing surrounding the aluminum block?

[Laloosh]

yea pretty much spot on. Its the biggest pos engine mount i have ever seen

[JimmyMac]

Wow, that's scary. I wonder if you pack the rubber bushing and rubber insert with some kind of epoxy or rubber filler, that it'll help prevent the rubber bushing from tearing. Basically what you did. But without the JB weld. Could be something for people to do that don't have tears in them yet. Hopefully that one single bolt will hold up to the torture test.

[gsrtype1]

great write up!! sub

[Laloosh]

I dunno but i cant wait to get my ecu back. I cannot move my engine for the life of me now. If you want to do a quick a easy test to see the shape of your mount do the following;

Jack up the drivers side of the car, put the car in gear, try to move the front tire back and forth, if the engine moves alot, ure fucked. Mine wiggled ALOT, after i filled it I can't get it to move no matter how hard i try to spin the wheel

[Hectik1]

I will have to try this.

[bioevolve]

That JB weld might crack on you, just check it after each run lol.

[javanc]

If you do it over again, use some polyurethane. Comes in tubes from the local home repair store. Also known as construction adhesive, its flexible, very sticky so no need for duct tape and wont harden and crack. And if you heat it up in the sun or the oven till its warm it will flow quite well.

[CraigHJr]

Yeah man why not just buy another factory mount till a solution comes out. JB Weld isn't exactly structual stuff. I would make a metal strap around the mount if anything so if it fails the motor cant fall down too far at least.

this is a good idea... there is room under the tranny mount to wrap a strap of metal or something around the mount. that MAY hold it up for a little bit, if you even realize that it broke... maybe wrap 20 coat hangers around it or something... lol

[Shanems3]

fuck it, make it a solid mount, we do it with the rear mm... do it with the tranny one, make it for track use only..

[Laloosh]

the trz derlin does a good job of support the mount...ill take my changes till cpe fabs something up

[Super Unique]

we need a sturdier mount made, with a built in secondary safety to prevent this stuff from getting out of control. After seeing the factory mount dissected like that, I find it hard to believe there isn't a federal recall on this car. That stock mount is scary.

[CraigHJr]

Chris you have the TRZ on there still? It can hold up the motor even with the side mount out or broken? I have the same mount so that would be a nice saftey feature. In the mean time I was going to make a little brace that bolts under the bolt head that would hold the motor up in the event that the rubber fails but, not if the bolt fails.

[Laloosh]

minus the vibes that 99 dollar mount is the best thing i ever bouht....im 100 percent sure its the reason my engine is not on the floor

[Shanems3]

i will be taking my mount off saturday, ill take pictures, 2 2008 models in my area just bit the dust..

(2) 2008 models dropped the engine because of the mounts? wow, not cool....

[Shanems3]

yes, 2 in my area, both 2008, one took out cv shaft and ripped up rear mm..

[Laloosh]

darksun's is a 2008 and his motor dropped. The recal reduce the chance of your motor dropping....however it still may drop as many 08 owners have shown

[phannarith]

chris that is fucking scary man, can't believe you drove around your car for so long with that shit.

[JimmyMac]

Did the mounts drop or did the bolts break? That's the main question for me.

I really don't mind the vibes. My SU mount vibrated more at idle.

3 if you want to count me...

[Laloosh]

There have been cases of all three: Some snapped the actually tranny bracket that the mount bolts into....some snapped the bolt...and some tore through the mount causing hte engine to just fall

[Shanems3]

it might be you, I know ryan broke his, you know Ryan.?? He is from BR..

when did yours break..

[Meder]

Mine was awhile ago but is a 2008. The bolt came loose and backed out, ive never heard of them breaking besides torn mounts

[Shanems3]

ahh, Ryans bolt backed out too.., one i get around to installing wot box, ill check mine..

Whats the eta on the cpe mount?

[samsel450r]

so what all did u do to take the mount out i know how to get to it and take it out but do u have to support the motor at all... i got the trz derlin mm to... does the rear motor mount hold up the motor when you take the tranny mount out?

[Shanems3]

put a floor jack under the tranny..

[bykeryder4life]

yeah id support it with something even if the tranny mount can hold the motor thats not good to do if you dont have to

[Shanems3]

the tranny mount is what you are taking out, not the rear mm, but yeah, the rear mm cannot support the engine and tranny, its only there for lateral movement..

[samsel450r]

WOW!!! i have mine out right now and it looks exaclly like laloosh's if not worse in some spots!!!! im going to buy me epoxy and fill it up....
