c4 trans simple questions

[red85]

You may have a C5 bell. Use the tc that you got with the bell and you shouldn't have any issues.I ran into a similar problem awhile back. The C5 bell is 5/8" deeper than the C4 so with the wrong tc, the front pump can't be engaged!

got a 6 bolt bell off a foxbody mustang. Retained my 2500 stahl converter (not the foxbody converter...this might be my problem..) Bolted right up. New 157t flexplate. I go to put the motor in a i get all the bellhousing bolts started. After that, i go to try to line up the 4 torque converter studs and the flexplate isnt in far enough. The studs line up perfect but just wont poke through the hole. Seems like the torque converter studs are too short. What is the problem here? Should i try to pull back on the TC? My 2500 stahl converter isnt as fat as my foxbody stock converter so im assuming this is probly the problem.

Are the studs about even with the face of the flexplate, or farther back ? If they're even, just take a screw driver and pull the converter forward enough to start one nut., Once you get that one on, the rest will be pulled thru the holes. If it's deeper, then like red85 said, you might have gotten a hold of a C-5 bell, it's deeper and uses a 164 tooth flexplate.

the studs are like right on the face..i would say 1/4" at most from touching the flexplate hole. I will try the screwdriver thing. I tried fitting a 164 tooth flexplate in the bell and it wont even spin without rubbing the walls. If pulling the TC forward doesnt work then i think i will put on the other TC. It's fatter and it will position the flexplate toward the motor more and allow the studs to go through.

is the bell housing tight against the block?

yes its fully contacted flat.

i cant even move the TC forward. Im gonna put the TC on that came with the bell and get a new flexplate with 11.5" bolt circle.

It really does sound to me like you got some sort of C5 bell. If the tc studs are 1/4" from the flexplate then by the time you make up the space to have the tc bolted up, you'll be close to 5/8". That just makes me think the bell is likely a C5 since it's roughly 5/8s deeper. Have you had the driveshaft in yet? That was where I figured out for sure that I had the wrong bell on my C4. The darn thing fit in there so tight that I knew something was up with overall length. Keep at it and keep telling us what's going on. We won't steer you wrong. Honest! ...That is unless you want to get into another stupid EFI vs carb argument LOL!

the guy i bought the bell from was positive it came off a 5.0 fox body mustang. I dont have the matching TC on it thats why was saying if i used the matching TC it might work because the 2 TC's are different thicknesses. ( sorry run-on sentance) just gotta get the right flex plate now..seems hard to find

Fox Stangs never came with C-4's, so if what he told you is true, then you got a C-5 bell. I was thinking these were 164 tooth only, but I could be wrong there.

what do u think is my best option? I really dont kno what to buy anymore. I know with the mustang TC it will make the flexplate stick closer to the engine and the TC studs will be able to poke through the flexplate holes. Thats about all i can think of. Does this sound reasonable?

i need a 157t flexplate with a 11.5 bolt circle and weighted! Ive looked all over Ebay and summit Racing and i cannot find this! If anyone could tell me where these are hiding i would thank u so much!

 

[baddad457]

The converter studs need to at least poke thru far enough to get a full nut and a tad more. Just as long as they're not sticking thru more than the thickness of the counterweight.

 

[red85]

What about getting a C5 tc from a tranny shop? Either that or get a 164 tooth tc and bell. I run a 164 tooth setup in my truck and I have no clearance issues. You should be able to find that stuff a little easier. Look for an older Crown Vic or Grand Marquis that came with a C4.

just noticed my trans does not have a kickdown cable. Its a manual valve body, does it still need the cable? If so where is a good cable kit to buy? My carb is a 4bbl Edelbrock.

No cable, it will be controlled with a vaccum modulator
