I have a 85 Caprice Classic which still has the factory 700r4 in it. I bolted the trans up to the 5.3 LS last night but seen that 1. the flywheel to torque converter holes are off a little bit and 2. when we turn the motor over to access the bolt holes the flywheel and the converter spins together. I was told it might be binded up inside, I just wanted to get some more info from you guys before I got pulling the trans off and trying to do it all over again. Thanks!

 

Is the torque convertor all the way back engauged in front pump of tranny. If not you could break front pump gears in tranny. Usually when its rite you can spin convertor till convertor/flywheel holes match up.

 

There are 3 distinct "clicks" when you are pushing the converter onto the shaft. When it's on right, you will need to pull the converter BACK a little bit towards the flwheel.

Another concern....I an not sure about a transmission from '95, but the truck "LS" motors, (4.8, 5.3, 6.0 and 6.2) have a different flywheel/converter than the true "car" LS motors (LS1, LS2, LS3, etc. I would bet that your converter isn't lining up because you are mixing a truck motor and a car transmission. I could be wrong though.

 

is the flywheel dished ,, if so you need this

you also need to elongate the converter bolt holes toward the center of the flexplate approximately 1/8 of an inch ,,, a rattail file works well for this purpose , or a dremel tool

 

The 5.3 Ls tranny has a smaller nub that goes into crank than 7oor4 dont they. so could hole on crank be to small for larger nub on 700r4 convertor?

 

I slotted the mounting holes on mine. Do you have the flywheel then the spacer?

 

yes it's a 03 silverado 5.3 going to a 85 chevy caprice 700r4...do i need to go to a different flywheel and if so, do you have any recommendations

 

No I have the spacer then flywheel. Right now the torque converter and flywheel are so close that when I turn the balancer the flywheel and converter move together.

 

My torque converter had a bit of play between the fly wheel and itself. It was not tight either, I could spin it


How are you guys doing your kick down cables?
