I put a TH400 in my car this year and I bought a TCI flexplate from LS1speed specifically for a LS1 TH400. I bought a brand new stock starter and when I try to start the car it just grinds. I tried shimming the starter and it made it worse. I am not sure if I am supposed to use a different starter or what I should do. If anybody can help me, it would be greatly appreciated. PM me or post on here or email me direct at tmorales@wfwhelan.com

Thanks.

whats the flywheel andstarter part numbers?

 

I am not sure on the stock starter part # but for the flexplate it is a TCI part # TCI399753. Do I need to use a different starter or something?

 

are you sure its the starter grinding on it? have you tried turning the motor by hand? i had to grind down the converter bolts when i installeed that flywheel cause they were hitting some bolts on the rear enginecover.

 

All I know is that I put a brand new stock starter in and the TCI flexplate part # 399753 and it grinds bad whenever I try to start it. Any help please!

 

is the flywheel flat...on backwards? using a spacer on the wrong side?

 

all fixed, thanks for all of the help everybody, the car is up and running now.

 

kwiw, what was the issue? Improperly installed flexplate I am guessing.

No spacer is needed with the ATI or TCI models FWIW.

 

For some reason I had to shim the starteron the outside bolt. It was weird because I ahve never had to do that before but I had to this time. It works now so that is all that matters.

Thanks.
