Resolved 1G - Transmission mount doesn't reach

[silentsnow31802]

After all the work getting my transmission stuff done I go to bolt it back in and found this...

The mount doesnt reach the transmission.
Its either sitting too high or the holes do not line up at all. Almost as if the mount needs to be lower.
I noticed before I removed the transmission this mount was at an angle but I assumed it was because the trans was being held in with hopes and dreams instead of real hardware.

Am I missing something? Wrong mount? Something seriously broken?

Are all the other mounts tight? You may have to loosen them and raise the trans up a little. It looks like it’s within reach if you jacked it up a little bit. Although, the side view picture makes it look a little worse.

The other mounts are tight. They are aftermarket and pretty stiff. Not much wiggle room even when loosened but ill give that a shot.
I fear its so far off if I make it fit as it is itll pull the bolt out of the transmission again. Its done this once already and I had to repair the thread. You can see the repaired one in the first picture.
Its about 1/2 to 3/4 inch off.

Oh another thing that seems odd is nothing is at an angle. The trans and mount are parallel with each other. If I jack up that side itll pivot on the mounts and come up at an angle wont it?

Is there anything supporting it besides the other mounts? Looks like you just need to jack it up. First trans install? This is common.

As pauleyman said jack it up and see if they line up. Once the mount is level with the engine if the bolt holes are still off you may need to use a ratchet strap to pull the engine over a bit to get the holes lined up. Aftermarket mounts are not going to line up as well as OEM in most cases. I would not worry about the bolt pulling out of the transmission due to "making it fit" the only reason that bolt hole would have given up its threads is from someone cross threading a bolt or putting the wrong size bolt in. The force the bolts experience when the car is driven is way more force than prying the mounts around to "make it fit" ever will cause.

Agreed with others. Loosen the d/s center bolt a bit, and loosen both roll stop mount bolts on the subframe, and start Jacking under the tranny to see if you can make up the gap. Then get the trans mount bolts fully into the trans threads before tightening anything else.

Not my first rodeo. Just not familiar with DSMs and I got this car missing a lot of parts that should have been reinstalled when the engine got put back together. Worried I was either missing something or something wasnt right. When I got the car this mount was ripped out of the transmission so it not lining up was a re flag to me.

I tried jacking it up and the car starts to lift before the mount lines up. Ill take a shot at loosening up all the other mounts to get it closer. Ratchet strap if I have to. You do make a good point about the stress when the car is running. Didnt think of that.

Thanks for confirming. Will give this a shot this weekend once I have some time. General consensus here is make it fit itll be fine . Which I now agree with. Ill let you all know how it goes!

 

[silentsnow31802]

So I loosened all the motor mounts and jacked the transmission up until the car was lifting of the jack stands. Put a ratchet strap around the trans then around the subframe to line up the holes.
Was able to get the furthest left bolt all the way down but the left bolt that was helicoiled pulled the coil out. Looks like ill need to tap the hole larger and get some bigger hardware in it. The hole us just a hair too large to hold a helicoil firmly.

I removed the mount from the... other mount... and set it on top of the transmission. Its still sitting quite a bit low to line up. I cannot get the transmission up any higher without removing motor mounts at this point.
Possible my aftermarket mounts are junk?

Bolt the mount to the trans first. Then install through bolt. Tighten frame rail mount last and use it to draw everything into place.

Also verify you have the 4 proper engine/trans mounts. Awd, Fwd, automatic are all different.

I thought about this earlier, but then I thought that they were previously installed in the car. Maybe not??

Yes I thought about mouting to the trans first. Ill give that a shot.
Im pretty sure the mounts are the correct ones. The car was running and driving before I tore it apart. Had been for a while.

If theyre different enough that you cannot bolt the engine in they have to be the right ones. The car ran and drove for quite a few months before I purchased it.

Just reaching here, but the roll stops mount to subframes while the d/s engine mount and trans are directly to the frame. If some kind of improper subframe bushings were used or misinstalled then alignment of all 4 mount would be off. Aluminum threads always make me nervous.

 

[dwb]

This is an aftermarket mount. Has it ever been installed properly? Do you have an OEM mount you can try?

I agree about the aluminum threads. That is why im trying to see if something is off before I keep blowing up the upper mounting points of this transmission.
I had a look at the mounting for both front crossmembers. I see there are 6 mounting points. 4 for the rear most and 2 on the front most.
I do notice the rear most crossmember has two different bolts on the rear two mounts. Not surprised there being the other random hardware ive found. But this obviously means this part has been removed at some point for who knows what reason.
While old, warn, and beat up, I do not see anything missing from the mounting points.
Here are some pictures of the mounting....

I do not know if its ever been installed properly. What is happening now was the same as when I got the car. I was not the one that installed those mounts.
All 4 have been replaced. They are AVID mounts. Not sure if these are good quality or not.
I do not have a stock mount I can try. At this point it could be any of them since they've all been replaced with aftermarket.
I do not want to have to purchase stock mounts but I will if I need to. Just not at that point yet. Want to make sure everything else is good before I blame the mounts.

The metal brackets that bolt to the trans and engine have numbers stamped on them. What are those numbers?

Front - 344
Rear - 494B
Trans - 22-H

Looks like you’ve got a few of the wrong mounting brackets.

The 1G AWD M/T rear is supposed to be 195 and front is supposed to be 347.

See: Please identify these and 1G motor mount bracket

Well that explains that....
Could my aftermarket mounts be wrong also? I dont see any actual part numbers on them.

 

[danl]

Clearly the engine brackets are incorrect. Just to amuse us, can you take a picture of the timing belt side engine mount just to make sure someone didn’t put a hacked 1.8L mount on when it should have a 2.0L mount.

Could be, but I certainly don’t have a good way of telling without some identifiers. Others may have tips or tricks here to offer.

Was everything mounted in the car at any point in time that you know of with the hardware you are intending to use? Or are you putting it together?

This is the only picture I have at the moment. Ill have to take a better one tomorrow when I get a chance to look at the car again.

The car came to me running and driving. I drove it off the trailer and into my garage. My nephew drove it around for a while before selling it to me. He got it from someone that seemed to want to fix it up but lost interest and threw it together to sell it.
The starter would grind when starting the engine which prompted this whole transmission removal.
Found a lot of the wrong hardware installed into places and some holes were stripped and needed to be repaired. Also found a couple cracks in the trans housing where it mounted to the engine block that needed to be repaired.
The transmission mount I am having a hard time with I never saw installed correctly. It was always at a downward angle with 1 bolt ripped out along with a helicoil a previous owner tried to use to repair it.

So long story short everything was mounted when I got it but not with the same hardware (bolt/nut wise) but it is the same mount wise. I had to replace quite a lot of bolts with OEM Mitsubishi bolts.

The awd and fwd front roll stoppers are not interchangeable. The rear roll stoppers are different between automatic and manual cars.

I’m not sure about the trans mount that bolts to the frame rail.

Yea ill have to source those and replace them. Ill have a thorough check at all of them now that I know.
On a positive note it looks like my transmission bracket is correct.

Here is the timing belt side mount.

Boosted fab makes brackets, I’m sure you can find some used ones too though.
