Are these the right parts from summit ?

Also , Whats needed to repalce both these mounts/bushings ?

Thanks for any info ... :bow:

Not sure about the bushings, but the transmission mount is easy... takes 30 minutes at most. If I recall correctly, one bolt and a jack to do the swap, that's it.

easiest to do them both at the same time.

should just need some basic, metric sockets (13, 15, maybe a 17), some extensions, metric end wrenches.

drop the trans crossmember (4 bolts)to get the tail of the trans lower so you can get better access to the torque arm bushing. it's a bit of a pain to move the front of the TA out of the way to slide the TA-mount in and out...but it can be done. have a piece of wood, or crowbar handy for some leverage.

and to put the TA bushing into the original mount, you need to grind off rivets holding the stock bushing. then reinstall the new one with supplied bolts. not a big deal unless you don't have a grinder. but it could be done with a dremel, or even a hand file with enough patience.

or i would be willing to be $10 to a mechanic and they'd grind em off for you.

Thanks for the info , i will do this soon since . i can see the transmission mount move when i push up on the driveshaft .

just a question i was getting a little play from my driveshaft as it goes into my transmission output seal , the seal is not leaking . Is there suppose to be any play at all or is a little ok ?

I/ Am Jacking up the car as soon as i am done typing . and probally will have another question or two after its done . so ill post it here .....



1st question how should i jack it up ? I mean can i do it with just the rear in the air ? with the frame on jackstands . will it be high enough ?

i have one 3 ton floor jack , 2 ton compact jack , and two jack stands .

what would you do ?

NEED HELP !!

I cant get the outer tourqe arm mount off ? that very top bolt is way to long to take out . ????:confused:

lower the jack down.....it should slide out

if its the bolt type slide the bolt back and take it off, if it has a studd lower the trans as much as you can

will lowering the tail of the transmission the can i get the top long bolt out ?

its the stud , and i did not try lowering it , so ill go give it a try thanks for a quick reply .

btw it started to rain so i came inside to post the pics . :cool:

will lowering the tail of the transmission the can i get the top long bolt out ?

yeah should be able to.......is it a bolt or a stud.

The bolt should go thru from the pass side with a nut on the D side you can just slide it over and take it off.

If its a stud(welded to the mounting plae) just lower the trans enough to slide it out.....


HURRY UP....sat. night got to go pick up some girls!!!

here is a pic tell me what you thing ????


I cant get it ????

?????????:confused:

i have the T/A up out of the way but cant get it out with those two suds in the way , ????

man someone put that top bolt in backwards.....if it came in from the other side you could slide it over and turn the mount down and pull it out.


The trans won't go any lower?

i had the trans rebuilt so i bet he did that **** !


What can i do ????


Cut it off ? with what all i have is a dermal ???


what you sugest?

man this sucks . what could i do ?


is it possiably to drill out the rivits and install the bushings they way it is now ?


could you think a dermal can fit up there and cut the head of that stud ?


let me know before you get them girls :cool:

what I would do...

take your dremel and a cut off wheel to cut the rivets out, pry it out etc.

and just put it in while the top stays in the car.....the othe side of the mount you can just take off and do.





I would say cut that bolt but then you can't put one back in there.......so go with plan A for now.




I thought you were going to get the girls......I'm too old I can't get em anymore

ok i just put the TA back toghter and installed my new transmission mount .

on the test drive theres alot of virbration , did i mess my my pioion angle up , Hows that work ?

Did the mount have a little metal plate? on the backside....


If it did then you can leave it off....its pretty common for those to vibrate.




What did you do with the T/A mount?

No plate it was all one unit . As for the T/A Mount i just put it back toghter like it oringally was .

i wasnt gona leave it on jack stands for the week end .

so you think i can cut off all 4 rivets and pry the 2 t/a bushings out ? and install the new ones like that in the picture ???

what do you mean by " the othe side of the mount you can just take off and do. " ?

not sure why you would have a vibration....maybe just feeling more from the new mount.
the T/A mount is like a clam shell...the outer part comes off.......you slide it forward or back and lift it...

the other part you could do on the car.

I cant get the outer clam shell off because the top bolt is revered , I cant rotate the outer shell at all to get it to release .


and even if i did it would still be attaced to the stud . man my luck , it had to be the last transmission rebuilt because it was a total new transmission the 2nd time , and on the transmission mount there was one 13 mm and one 14 mm bolts and one was a little shorter , he must of lost the oringnal bolt . , But the transmission works great . !

ok this is really bothering me , what do I do ? I only have the floor jack for one more day only . and i have not try to do anything else yet . I really want to replace this bushing ?


THIS IS THE PROMBLEM : THE BOLT IS REVERSED . WHAT COULD I DO ?

Hmmmm..........you could approach this by doing the following;

1) Find a shop that has a lift - raise the car. Get an adj. stand or jack and place under the transmission. Remove the crossmember and lower the transmission (note it will still be attached to the engine and the rest of the drivetrain - be careful) until you get the clearance to remove the stud. Once you remove the stud, raise the transmission to the previous height as to relieve the stresses put on the engine mounts, and driveshaft connections to the transmission and rear end. When installing the T/A mount - just remember to put the stud in the other way (threads facing the driver side of the car)

2) If the above doesn't work or you can't get access to a shop with a lift, then you would need to cut the stud and get a replacement. As with the above just remember to put the stud in the other way (threads facing the driver side of the car).

1) I lowered the acdelco jack holding the transmission up all the way off . the transmission actually in the picture is as low as it can go , the jack is not even touching the transmission .

2)what can I use to cut the Bolt stud off ? I work at a Quick lube with a pit . but cant work on it in the pit bay , we have a sissor lift that wont work it covers up the area i need to work at .

3) how much would a reasonable exhaust shop charge to unbolt the crossmember and cut that bolt head off that bolt ? or would they even need to unbolt the crossmember ? Might be able to , form the front get to the bolt . And cut it off with a thorch ? And replace it the right way with a replacement ?

do you have a dremel?

Yes i have a dermal with the cut off disk type attactment .

The floor jack wont work anymore , its leaked out to much fluid . and was spraying it out , this is why we didnt use it anymore at the shop., And that little ac delco jack is all i have now .

But please tell me ya all think ? :bow:

grind the rivets down with the dremel...and slide the old mounts out. Looks like you can bolt the new one in without taking it off.



Don't cut that top bolt man.......You still won't be able to put a new one in.

ya i just try grinding first , i think i can grind them down and pry off the old bushings. i can try with my shop die grinder and try to get as many as i can from the shop's pit tommrow , ill let you all know what happens .


Thanks for all the input guys :) :bow:

don't cut anything----take out the driveshaft then unbolt the tailshaft then you can put it right

don't cut anything----take out the driveshaft then unbolt the tailshaft then you can put it right

could you explain this a little more , How would i separate the tailshaft , and driveshaft . I never did anything like that before ? Thanks

take the drive shaft out....4 bolts on the rear u-joint straps DS slides out

4 bolts in the tail houseing of trans.....might have to pull the speed sensor out, take the tail shaft off. It has an oring in it...seal it up with some silicone or something when you put it back on.....

don't forget to put a bucket under it to catch tranny fluid that will come out -not much but enough to make a mess-sensor should stay in just take off cable
