Powerglide startup
Posted by: Westds ()
Date: January 17, 2018 06:42PM

I want to start up my 140 Powerglide engine on my test stand. I am worried that the Powerglide is in gear and I do not know what to expect. Will it run without changing the position of the gear selector? Will the drive shaft yokes back out of the differential? I would like to check out the seals before I install this powertrain in my Lakewood. Would appreciate any input as I am not a A/T mechanic.

The Diff is a 1964 and the yokes are not bolted on the EM.

I do not run a PG engine on the stand with a trans axle bolted on, I have a dummy Torque converter I use and run a PG engine with no transaxle for 2 reasons, 1 you do not want to run the PG dry with no ATF, and 2 when installing the power pack you want to do it dry as when you hook up the shift cable trans fluid runs everywhere, So either make a Dummy TC, or bolt a flywheel on temporary to run the engine, Then bolt the transaxle on dry, and fill it with ATF once the cable is installed.

Thanks Dave
The engine has been run with a manual transaxle and it is fine. I was concerned about the torque converter seal. I did not want to install the powertrain and deal with a problem. I guess I will just go ahead and install the unit and hope for the best. The diff and transmission have been resealed.

Triggered my memory...

Vaguely recall my old Corvair mechanic had made a PG cable "seal" by using the end of an old PG cable. Cut it off and welded(?) / soldered(?) the metal end / tip closed.

Probably too much work for an individual / one time use...

How dry is the PG system? New torque converter or drained used? Either way you can put 3 qts of trans fluid in so it is not dry.
Do you have any round turn signal flashers? They fit in the axle seals perfectly and can stay there until you install the axles. As far as the trans shift cable I use a plastic plug for the hole but keep in mind that the dipstick has to be installed and that goes through the firewall, very hard to line up putting the engine in if at all. So the trans would be drained again anyway.

I just put a torque converter seal in and it leaked right off the bat! But it sealed up as it ran some. after about 20 miles it was virtually dry.

The torque converter is rebuilt so it was dry, I put about a qt. in it before I installed it. I don't have any flashers but I will look for something to plug the openings. My concern remains will the transmission remain in the low gear it appears to be in so I can install the shift cable? Will running it in gear on the bench destroy anything?
