I have to move my car about 75 miles to my shop. Will towing it with the drive shaft hooked up damage the power glide transmission. I know you can't tow the late model cars this way.

Don't tow it with the driveshaft hooked up. It could be pulled a short distance at low speed with it attached - but not that far and at highway speeds. Take the rear U-joint apart and tie the end up securely and go - 15 min. off and 15 min. on to save the PG.

just tie up the drive shaft and go. what is the 15 min on 15 min off for? a waste of time?

Probably to reinforce the idea that it is a simple thing, if someone hasnt taken apart the rear u-joint it may seem like a lot of work.

If the car runs, you could leave the engine running transmission in neutral and go that way the front pump on the trans is operating. I've towed a car on a tow dolly that way before, not 75 miles though.
Just as easy to pop the driveshaft out of the pinion yoke though.

Dont forget to drain the trans before pulling the shaft out . :D

interesting note about powerglides. it's one of the few transmissions that you can push start the car. the pump works differently than a 350 TH. you have to get up considerable speed though.

It is all totally dependant on which model of PG is in the car----------------and I can't answer this question because I'm not an auto tranny guru.
BUT, here is what I do know. SOMETIME up into the 60s, the PG trannys had BOTH a front and rear pump. And then sometime in the mid 60s, the PG was changed and only had a FRONT pump. Thus, if a PG is the version that has a rear pump, you are OK to tow it with the driveshaft in place. Also, you CAN push start a PG car that has the rear pump (have to get up to about 25-30mph, then slam it into gear). And if it is the later version PG and does not have a rear pump, then you need to pull the driveshaft for towing a long distance (over 50mi). Also, a PG that does not have a rear pump cannot be push started.

Soooooooooooooo, here is the big question. Who knows when the PG changed from front/rear pumps to only a front pump? :confused:

'66 had the rear pump. '67 did not.

it was around 1965 or so when we were push starting them. we would start out with the tranny in drive.

This explains 62 to 66 PG's

As I mentioned earlier, I'm NOT an auto tranny guru (actually I dispise them!!!), but being a diehard Chevy nut, I've had limited experience with PGs in the past.
On the VERY FEW ocassions that I've helped to push start a PG car, I was informed that if you leave the tranny in neutral until about 25-30mph, then quickly drop it in gear, the rear pump produces a sudden surge of pressure and quickly engages the engine which will probably start it faster. So, that's how we always did it with good success. :thumbsup:
