Hey guys my car has been leaking trans fluid like a siv, so i yanked my engine and am getting ready to pull my torque converter and am curious if when i pull it if fluid will leak everywhere? Also im not quite sure where it's leaking from but think it might be the torque converter seal in my input shaft.
If you guys have any advice for me, it would be much appreciated. Thanks |

C4/C6/FMX? I just had to remove my C6 to get at flexplate/converter due to some issues and almost no fluid spilled when I removed TC from front pump/stator while on level ground, but this could be a sign of another issue. If you are having leak issues with a C6- it could be the dipstick's O-ring or the converter drain back check valve is stuck open-this allows the fluid inside the converter to drain back into pan which raises the fluid level enough to overflow the dipstick O-ring and/or come out the trans case's vent. The drain back check valve is located within the stator that bolts to the front pump housing. If this check valve gets stuck closed the trans will overheat and push fluid out of the vent, since there would be no fluid flow to the cooler. If the converter bushing inside the front pump housing is overly wore this could be another potential issue that leads to a converter's hub seal leaking. Hope this helps. No on to fixing my C6 issues.

Its a c6. I was told its leaking from either the pump seal or the TQ seal on the input shaft.
How do i go about pulling the TC? Edited by Postma98 - 21-June-2017 at 7:33AM |

Well if it is in deed a bad torque converter you will at least have to pull the transmission or it may be easier to pull the engine/trans together as one unit, this really depends on how much you like to work on your back or if you are lucky you have access to a lift. This is what I just found inside my valve body causing my converter to dump fluid inside the trans, which delays transmission engagement at start-up. The converter relief ball was pushed through the separator plate.
Looks like it was shot with a .22! To pull the trans you will need to remove the following: trans fluid, starter, drive shaft, headers/exhaust system(possibly, but sometimes not necessary), fluid lines to trans case, dip stick tube, transmission jack or just a hydraulic jack with a piece of 2x6 under the trans pan using a ratchet strap to hold trans to jack so it won't fall over (then raise trans), trans cross member, speedo cable, kick down rod, shift linkage, trans bell housing to engine bolts(the top ones can sometimes be easier to access from above, behind the intake manifold, vacuum line to modulator, the converter/flex plate shield(located at the front lower portion of bell housing), the (4) 9/16" torque converter to flex plate nuts(must use 1/2" drive socket wrench with 15/16" socket-460's anyhow-to turn crank shaft to get at all four nuts, Now you can move transmission away from engine with a little bit of rocking motion, just be careful, having a couple extra hands makes things much easier. Once you have enough room, you can grasp the TC and with aturning motion just pull it forward away from trans, the input shaft may come out with it, no big deal. Just make sure to reinstall the input shaft with the shaft's "dimple" facing outward/toward engine. To make transmission removal easier if on your back have vehicle at least 18" off the ground, BB bell housing is 18.5" tall. I hope I didn't leave anything out. Good luck.

A couple hard wiggles shook my TC right off😂 But i dont know how to tell if my pump seal is bad or not. Do I have to pull my stator and pump?

If you are already there, I would definitely install a new seal. You can remove the seal with an appropriate seal puller without having to remove the front pump then separate it from the stator. It would be best to suspend the transmission vertically before front pump removal, doing this keeps everything" in place", if a seal puller can not be located/used. Installing the seal can be accomplished with an appropriate seal driver or being very careful with a dead blow hammer(a 1' piece of PVC pipe that matches the O.D. of the seal can also be used to drive the seal into place) since the stator/input shaft is in the way(leaving the front pump installed). The more things you remove, the more of a chance for "bad things" to happen to an otherwise good transmission. Good luck.

something to check for is if the bushing in the pump is worn it's like a cam bearing that the convertor rides on, if its worn bad the convertor can be riding low, allowing the fluid to get out past the seal, something to consider! the seal should be flexible and still have a sharp lip on the edge

Not planning to pull my front pump, just going to replace the input shaft seal, if I have to tear past the pump then i will take it to a machine shop and have it built. I would like to have my heads and intake ported by a machine shop and have my heads rebuilt, so I'll fix my front seal and fill it up with trans fluid, if it still leaks I'll take it to the shop along with my heads and intake😂

What would you guys recommend for a torque converter stall in my 429 with 3.50 gears? Is 2000 too high?

Converter need to be matched to cam size, gears, and weight of car.

This chart may help with selection, totally agree what Allen said, have to take into account a few factors to successfully match a TC for an application.

A BBF usually likes and responds well to a camshaft that has 10-15 degrees more duration and .010-.015" more lift on the exhaust side, mostly due to their inherently poor exhaust port layout/flow, just saying.

252* advertized that's basically a stock replacement cam, i'd say about 268-280* if you want some cam sound and added torque and power with out getting too crazy those bigger cams are generally a little milder in a bigblock

206 sounds about right for a 252 cam kinda on the mild side unless that's what you want

Stock camshaft specs, note the intake/exhaust duration and lift differences/spread.

Comp had a 252 cam, they call it the Taxi cam because it's extremely fuel efficient and doesn't do much more than A to B. i knew a guy that ran the 252 in a 350 chevy, ran good just ran out of wind before anything got going. he put his Crane Fireball 296 back in 252 doesn't need any stall converter at all, as the links above show 252 is very small / smaller than stock in most cases

Alright so i looked at the cam specs and don't know if I've been reading them wrong and figured i could save some time by just posting them.
Cam Style: Hydraulic flat tappet Basic Operating RPM Range: 800-4,800 Intake Duration at 050 inch Lift:206 Exhaust Duration at 050 inch Lift:206 Duration at 050 inch Lift:206 int./206 exh. Advertised Intake Duration:252 Advertised Exhaust Duration:252 Advertised Duration:252 int./252 exh. Intake Valve Lift with Factory Rocker Arm Ratio:0.468 in. Exhaust Valve Lift with Factory Rocker Arm Ratio:0.468 in. Valve Lift with Factory Rocker Arm Ratio:0.468 int./0.468 exh. Lobe Separation (degrees):110 The reason for such a low operating range is because i wanted a low end torquee cam for around town and short drives. AKA a tire smoking monster!!! what do you guys think? Edited by Postma98 - 25-June-2017 at 7:27AM |

What year 429? Is it factory stock or has it been rebuilt, if so what compression ratio? A high compression 429 will need a "larger" camshaft(more duration) to live on today's pump gas, it will bleed low rpm compression to aid in keeping detonation to a minimum. Having detailed engine specs are a must before an accurate camshaft recommendation can be given.
