C6 for a Novice
The subject here is a C6 which was installed by a second rate shade tree mechanic [me], installed without ever seeing one come out or go in. A transmission jack was used and the tranny slid up to the engine with no problem; the mount bolts bottomed out with fingers before a wrench was put on. The torque converter was bolted to the flex plate thru the inspection hole at the bottom of the engine. The torque converter took about 2 quarts of fluid before the tranny was put in and 3 quarts have been added thru the dipstick tube. The dipstick first shows fluid in the correct range and later shows fluid 2 or 3 inches up the dipstick. With the engine running, how long should it take for the tranny to pump up and shift into any gear? The tranny acts like it doesn't have any fluid at all. It sure would be a boner to have to pull that tranny without ever getting my machine on the road.

I don't think you have enough fluid in it yet. My C6 in my '71 takes 12 quarts of oil and it has a standard (not deep) pan. It could have splashed up the stick on yours because it bounced off the pan when you cranked it. What I mean by that is that what you had in the pan was picked up and what was in the converter made it to an empty pan which allowed it to splash.

Thanx to jds1971 & 4CAMMER72
I am told the C6 needs 11 or 12 quarts of fluid, and about 8 or 9 of this will be in the torque converter. Another unasked/unanswered question: What happens if there is too much fluid in the tranny? The dipstick has a mark which says "...don't add fluid if the level is above .." this mark.

It'll come in contact with the rotating parts (sorry, don't know the correct terminology) and cause it to aeriate- meaning it will foam and when the foam reaches the pump, it ruins the pump.
Glad everything worked out for you-

Thanx for your reply.
Two quarts of fluid were added and the dipstick now shows the correct level of fluid -- between the arrows on the dipstick, but the machine still will not move. Two things will get checked tomorrow: see whether or not the shifter is working and get the back wheels off the ground to see if they will move.

you are filling the trans and checking the fluid level with the ingine running at idle aren't you? if you are checking it not running you are going to be real low on actual fluid.

what do you mean. did you hook up the vacuum modulator in the rear of the tranny to the intake manifold. that would cause the no shift problem. are you adding fluid while in neutral. then put it into drive, while holding the brake, for five seconds, then reverse, then back to neutral and checking. is your torque converter seated properly, because the c-6 is kind of bitch that way. there are 3 different seating positions it goes through. there is a lot of fluid that goes into it, so dont be hesitant to add some more, just make sure you add it in neutral and while idleing.

C6 for a Novice
A quick reply was started a few minutes ago and a phatt phinger hit the wrong key. The meat of the other attempt will be repeated here.
Thanx to 4cam and Willow:
<>The vacuum module was hooked to the vacuum manifold [a post, at rear of carb] before the exhaust was bolted on [the engine runs/sounds much better with the exhaust pipe, mufflers, and tail pipes in place....back pressure??].
<>The fluid was checked with the engine warmed up, at idle speed, in park.
<>Seating the torque converter is a new twist. What goes on to do this??
Items to check/do next:
<>Check the torque converter nuts at the inspection plate.
<>Shift to reverse for 5 seconds etc per message from Willow.
<>Vacuum module connection to vacuum manifold. It is possible that this line is stopped up or has been knocked loose; say, during bolting up the rear engine/tranny mount or messing with some other things on top of the engine.
<>Get the rear wheels off the ground to see if there is any motion.
A friend here was needling me about "....didja hook up the shifter..." which is a step he would lilkely leave out.
Again, thanx guys

converter seating
the c6 converter has two sets of splines and a set of groves (two- the side of the shaft). you must make sure that it goes all the way back in. just keep twisting and gently pushing it in. once you think you have it, do it again to be sure. when i set my converter, it was nearly touching the back of the bellhouseing. a way to find out if its not seated properly is that if you have to keep tightning the torque converter bolts on the flywheel after awhile, its not seated in there correct. thats really all there is to it.

C6 for a Novice
Enough!! Tomorrow my friendly tranny shop is coming after my machine. Yesterday with fluid at the correct level, a wheel chirped on pavement and I nearly lost control; then wheel spin in the grass and now nothing seems to work [ it won't move in any direction]. The tranny leaked a steady stream of fluid out of the bottom of the dipstick tube.
Again, thanx for your replies and offers to help. The next post will be whatever I find out from the shop.

Yomow: the first part of your message [12-10, 3:14PM] sounds like the tranny will have to come out to fix a broken pump gear. The second part of your message sounds like a hook up will happen when the engine is revved to 2500 rpm and then maybe things will be OK; I would dearly love to believe/do this second part.
My friendly tranny mechanic is scheduled to send a roll back tomorrow midday. Do I cancel??
Either way, your response is appreciated.

Nope , pull it ! When installing a conv. you need to make sure you turn the converter & push it inwards . You should not be able to put your fingers between the conv. & trans. if you can It's gotta go in more ,the tips of your finger's should not go near the pump . that's when it's in all the way. I broke a pump gear because I Thought I was the man . Not I have alway's learned the hard way . But I found out your dumb when you don't ask . I'm 51 year's old & heck I'm still learning . Ask Question's These people are the smart one's . I'm very gratefull for there info. Been a mech. for 38 year's my Dad used to have gas station's . Don

well yea, you shouldnt be able to fit your fingers into the back of the houseing, but the converter sure as hell better not be rubbing the houseing. that wouldnt be right. i can get my fingers up to the first knuckle in before they are cut out of the gap, which isnt much. just trust yourself and do it man, thats all that you need to do.
