Well guys, first off let me say I'm sorry for having so many questions lately. I have been reading and researching but haven't found anything pertaining to my questions..

So id like to thank you all again..


But anyways, i sold my f150, and i'm picking up a 2g talon.. It has the 6 bolt motor swap done to it, but the transmission won't go into gear.. It may need bled because the last owner didn't know how to work on it.. I'm picking her up for 1500$! No Rust NOTHING!

But worst case i need to replace trans.. Well; i have a AWD 5 speed trans out of a 96 GSX.. Will this trans work on a 2g 6bolt motored swapped talon??

What about the clutch and flywheel as well? Will they work? If not what do i all need?
 
Any transmission 1g or 2g will bolt to that engine, they aren't different between 6 and 7 bolt. The big differences are between 1g and 2g. You much use a 2g transmission because of the mount bracket locations. you can use the 96 trans as long as you have the transfer case for that transmission.
 
Wait, I'm not following what your saying..

What i got out of it is, 7 bolt and 6 bolt trans are pretty much interchangeable..

But 6 bolt and 7 bolt transfer cases are different?

What about flywheels?
 
In a 2g you need a trans from a 2g. A 1g or 2g trans will both bolt up to a 6 or 7bolt block but the mounts are different where the motor / trans mounts bolt up to the chassis. you will need a 6 bolt AWD flywheel and a 2g 95-99 transmission. You will also need the correct transfer case for the trans if the trans is from 95-96 you will need a 95-96 transfer case, if its a 97-99 trans you will need a 97-99 trasfercase. The 95-96 and 97-99 Transmissions have different drive ratios so you must use the matching transfer case.
 
Hes syaing to use a 2g transmission because of the placemen of the motor mounts. The flywheel needs to match the crank being used. 6bolt flywheel needs to be used on a 6 bolt motor, 7 bolt same. Im pretty sure they need to match the trans in the sense of it being a auto or 5 speed.
 
Okay I'm still a little confused, sorry its late and I'm tired..

i will be owning a 97 eagle talon tsi AWD with the 6Bolt motor swap done to it..

It may need a new trans, not sure. but i have a 2g GSX Trans (7bolt or w.e)

Can i literally, take the trans out of the 2g talon.. and put the trans from the GSX into it? along with the guts (aka the flywheel and clutch?) and literally do a direct swap?

Im assuming the trans in it now is still from the 2g..

No the transfer cases aren't different. There is no difference between the drivetrain parts for 6 or 7 bolt, only the differences in the flywheel. Everything else is interchangeable. The thing with the transfer case is having the right case for the right transmission. With 2g's there are 2 different ratio's available, you have to make sure that you have the case matched with the transmission.

You can use the trans as long as you use the correct transfer case, you need a 6 bolt awd flywheel, clutch is the same for all years.

You can use your gsx tranny with the talon but, make sure you have a 6 bolt flywheel.:thumb:

I did some research about 95s and 96s and the gear ratios for their transmissions were different from the 2gbs, so I don't know what issue that may cause, it'll probably just be different driving it. Should bolt right up like everyone else said though.

It will damage your viscous coupler if you dont use the correct transfer case.
 
Somebody really wants to confuse this guys. Lets break it down
Flywheel doesn't matter to transmission. There are AWD and FWD. You must use either a 6 bolt or 7 bolt depending on what motor you have. thats it for flywheel. 6 or 7 bolt and AWD FWD. Nothing more.

The 2g cars have different motor mounts so you must use a transmission meant to bolt into a 2g. You cannot use a 1g transmission Any 95-99 transmission will bolt in. So what's the difference in 2g transmissions? It's the front differential gear ratio. If you use a 95-96 transmission any 90-96 tcase will work. They are all the same ratio. Only 90spline count is different and it's only one with a different spline count. The tcases will interchange so it's possible to mix and match for the most part. All 91 up are 23 spline and will physically interchange (bolt up).
97-99 transmissions have a different front diff ratio and a transfercase ratio to match it. You cannot mix and match years here. If you use a 97-99 transmission you must use a 97-99 transfercase unless you took the transmission apart and change the front diff ring gear. All of this applies to manual transmissionis only. Clear as mud?
Just for reference the manual transmission rear end ratios are the same. The change is the front diff ratio. I don't know why they did it.

One last recap. the tcases will physically bolt up to any year provided you use the correct spline count so it's possible to get the wrong ratio. Make sure you have the right ratio for what you need. Every once in awhile somebody buys a 97 up tcase and tries to put it on a 96 or younger car. It will bolt up but you won't like the results. Try bolting up differnent circumference tires on the car front and rear. Same result.

All you have to do is make sure the flywheel is a 6 bolt awd flywheel, that's it.
 
The bell housing of the tranny should bolt up properly, 6 bolts i believe. But there is a thread that requires a longer screw that screws into the engine block first, then into the tranny. The screw hole is located in the back of the engine more towards the bottom though. It is directly above but slightly to the left of the first bell housing bolt screw in opening, if under the vehicle. maybe be easier to find using your finger than trying to stick your head all up in there. And also i have a 6 bolt swap in my 1g eclipse, needed a tranny though. Got one from the junk yard, didnt realize it was a 5 bolt and had the 5 bolt drivepalte and adapter plates. The bolt pattern did not match up in any way so i had to use the old 6 bolt driveplate and adapter plates. But as far as 6 bolt to 7 im not sure. But i know they call them bolt patterns for a reason.
 
Make sure you intermediate shaft works, I ran into this a little awhile ago. (not sure if this was discussed)The bracket differs between the years. And I believe 90-96 years are the same then 97-99 are different.
 
Any transmission 1g or 2g will bolt to that engine, they aren't different between 6 and 7 bolt. The big differences are between 1g and 2g. You much use a 2g transmission because of the mount bracket locations. you can use the 96 trans as long as you have the transfer case for that transmission.

Hey im converting my 93 7bolt na to manual transmission but im confused of what flywheel and clutch to use cus i have a 6bolt turbo tranny from a complete turbo part car i bought but just want to concerted to manual for now until i rebuilt the turbo engine any info you can share will be appreciated thanks
 
I assume the turbo transmission you are using is FWD? If so, you will need a 7-bolt FWD turbo flywheel. 7 bolts to bolt the thing to the crank and FWD turbo for proper positioning between the flywheel's ring gear diameter for the starter.

That would also necessitate a turbo clutch kit.
 
Yes its fwd

and do i have to also use 7 bolt turbo clutch

There is no such thing as a 7-bolt clutch. For the 4G63 application, the only differentiation between clutches is turbo or non-turbo. FWD turbo and AWD turbo use the same clutch kit. The non-turbo uses a completely different clutch kit.

Again, you need a turbo clutch kit.

ohhhh cool thank you so much i really appreciate so just buy a 7 bolt turbo flywheel and any turbo clutch dont matter if it's for 6 bolt or 7 bolt is all the same but it has to be Turbo right sorry to keep asking I'm just a little confused

There is no 6 bolt or 7 bolt clutch. All year turbo clutches are the same.
