The driveshaft will work fine.

As far as the torque converter:

Fill it with 1 qt before install. Push the converter into the pump while slowly turning it. It should clunk in 3 times. Once properly seated, the torque converter mounts should be about 3/4" to 1" below the bellhousing.

in my haynes manual it says that i will have to take off the exhaust around the catalytic converter.......is there any way of getting around this.......cuz i believe i will have to torch mine off cuz its rusted on there...........also it says that i should make sure the torque converter and the flexplate are still in the same alignment........well im going to put a new converter in there so how will i know how to align it?

also.....if i fill the tranny with the fluid will it get to the converter or do i have to physically fill the converter itself?

thanks

Don't know what to tell ya on the exhaust. When I swapped my trans I already had an aftermarket system on it. All I did was unbolt the y-pipe and let the exhaust hang.

The indexing of the converter and flexplate is probably just for balance purposes. Obviously there is nothing to index with a new converter.

For filling the trans: Before you install the converter, pour in 1 qt. I can't remember how much I filled the trans with before starting, but I think it was around 5 or 6 qts. Then check the fluid, add a qt, check the fluid, add a qt, check the fluid etc until you reach the proper fluid level. I think capacity is 12 qts, but check the manual on that one.

so the exhaust DID get in the way of your car?

does yours have a single catalytic converter off to the passenger side?

thanks for the help

in his sig it says catco cat, and the stock location would be on the passengers side after the y-pipe.

As long as you get the converter to seat all the way I dont see how it could be off. It just slids on.

You will probably have to disconnect the y pipe and converter. I have longtubes and duals on mine so it was easy for me to remove my entire exhaust.

I had to disconnect my headers to that kinda sucked.

This was my first time for pulling a trans also. It wasnt to hard at all. Just take the driveshaft loose from the rearend (4 bolts) then slid it forward and then slide it it. take the flywheel to converter bolts out (3) then Disconnect the bellhousing bolts (6). Pull the dipstick tube out, then disconnect the shifter cable, wires, and then the trans crossmember. Make for a jack with a piece of wood or a tranny jack is under the pan. Then slower it down some until you can get to the TV cable wire and tranny lines and disconnect them. Then bring it the rest of the way down and your done.

I havent went to reinstall it yet but I dont think it will be to bad. Just get it up enough to get the crossmember back on and go from there.

BTW Marc....I love that car man. Those rims look awesome with that two tone. I have two tone like that but mines red. I wish it was blue.

The reason I had to disconnect the exhaust is because in order to get to the bellhousing bolts you need to tilt the engine and trans a good bit. My Y-pipe interfered with my oil pan, preventing enough tilt to get to a couple of the bolts. You may not need to do this with a stock application - I don't know for sure. As it is the y-pipe sits real close to the pan. Maybe the stock piping isn't as close... I can't remember.

TBI305Camaro - Thanks for the compliments It seems back a year ago when it was painted I caught a lot of flack for the two-tone Everyone in person loves it though, even those who don't like two tone.
