Flashback of my 67 Impala rebuild a couple years ago. Thank you.

[@SouthpawAutoworks]

Right on. Thanks for dropping us a line, James.

[@johnkelly6942]

Just traded for a ‘55 Nomad (project car). It came with a 327 and aluminum PowerGlide which is being rebuilt as we speak. This video was very helpful as I now have a better idea how the work and what to look for when rebuilding.

[@SouthpawAutoworks]

Right on.

[@Whitley.Peterson]

Solid info! Keep it up. Y’all answered the questions I had as he explained the functions and purposes to external parts! Thank you!!

[@SouthpawAutoworks]

Right on! Thanks for dropping us a line!

[@Shalash87]

So you decided to go old school! Well looking forward to an FMX then, or even a Hydramatic!

[@SouthpawAutoworks]

I know, right!

[@daviddemarsh1371]

what you showed was great. Please finish the complete teardown and show the rebuild. Good work.

[@SouthpawAutoworks]

You're welcome

[@emilyramsey9079]

Would have been nice if you would of explained which clutch pack did what but was a good video. 👍

[@SouthpawAutoworks]

When time permits, we could dedicate a video to that topic.

[@jraydelatorre]

Nice video Robert Not a whole lot to the powerglide but take some skill and knowledge to make one handle horsepower

[@SouthpawAutoworks]

We'll have to add one of those builds to the list. Thanks for watching, and dropping us a line.

I bought a modified powerglide a few years back but noticed the output shaft has some play to it. Its with a short tailhousing. Is this correct or is there missing/broken parts most likely? Awesome breakdown eitherway!

[@SouthpawAutoworks]

The positive feedback is appreciated. Automatic transmissions will have end-play (front-to-rear movement). They have both front and rear end-play specs (thousands of an inch). Regarding the output shaft, are you talking about front-to-rear movement? Or are we talking about up and down movement?

[@hasseboulen]

@@SouthpawAutoworks It has up and down movement, to where the output shaft can come in contact with the inner rim and thus nullifying any seal aswell. Edit: To clarify, the output shaft can be tilted to touch the edge of where the yoke would normally be up against.

[@SouthpawAutoworks]

I don't have the PowerGlide unit handy to see what a known good unit will do (in other words, how far the shaft will travel up and down). However, I'm thinking this is normal. Here's why... Picture the trans being fully assembled. The extension housing is outfitted with a bushing (and of course a seal). In this instance, the output shaft can be moved up and down, to some degree. - However, when we install the driveshaft into the rear of the trans, the slip yoke will spline with the output shaft. At this point, the slip yoke is being supported by the bushing, in the extension housing...minimizing any up and down movement of the slip yoke. And now the output shaft is being supported by the slip yoke (they're splined together)...which minimizes up and down movement of the output shaft. Once again, I would need to inspect a known good unit, to see what's normal. If it turned out that the up & down movement was beyond "spec", then I'd be looking at the case bushing, etc. Hope this helps.

What happends if the "bandadjustment" is to tight or to lose? I have seen people say after you tork it back it out 2 turns , 3 turns and 4 turns. So what happend if i only back it out 1 turn or lets say 5-6 turns?

[@SouthpawAutoworks]

If it's set too tight, the band will be dragging excessively on the drum, which will burn up the paper lining (friction material) on the band...and possibly damage the band surface on the drum. If it's set too loose, the band will not be able to clamp the drum enough to prevent the drum from rotating. This would result in a loss of a gear. Could also result in slipping, which could burn up the band.
