Does it slip in reverse also since low and reverse use the same clutches, (but reverse uses band also), I would say you have hard lip seals internal, and time for a rebuild, If you have ever rebuilt a transmission or if you want to the power glide is the easiest one to do! very few parts inside! Good Luck!

Yup, most likely hard seals or clutches completely worn out....

a band adjustment , the servo piston leaking by that applies the band ,

try a bottle of trans X ,, good stuff ,, it might be in the valve body too ,, something stuck

Nope pull it out to rebuild it. I just did mine last year for the first time ever and it was simple. I highly recommend The Powerglide Handbook I got from Summit for $17. Spend a couple days on the toilet with it (the book that is) before you pull it apart and you'll be a pro. It was nothing at all to rebuild it. Don't be scared. Here's the link to the book

I remeber the powerslide in my 67 Chevelle I had in highschool, the only way it would shift to second was if I lifted off the gas peddle then it would slide into gear!!!!:devil:

HA !!! sounds familiar :yes:

good trannys though, not the air cooled or cast iron though... i blew up a couple cast iron units. it was a pita with those. heavy suckers... buy a car ('55) and run it 'till the engine or trans blew then 327 & Muncie 'em :devil: love and hate. sometimes it was fun blowin' something up, other times it happened at the worst time or place :eek:


Hey Batman
i have an air cooled sitting here that's more than likely good... if ya lived closer Bruce i'd deliver it... but i wouldn't use it, i wouldn't think you'd use one either ;)

get yer Honey an OD Batman !!! :thumbsup:

could just be low on fluid... and or getting too hot... mine would slip all the time at temp., added a trans cooler, now it's fine....

They are a good trans if built right. We threw 2K hp at it, ran 6 sec 1/4, & over 200 mph with the Glide. There are certain "do's" & "don'ts" that can fry one in a hurry as well.

Once they start slipping you pretty much need to rebuild. I just went through this. I had a 6cyl PG behind a 400hp 327. I spent $900.00 to upgrade to manual valve body, the additional clutches used on V-8 setup and a steel pump? A steel something! Anyway. I love it. I didn't think I would like the full manual setup but it's fun with a Quarter Stick. Shifts hard. Not as fun if you have a column shift. Pull the pan. That will usually tell you if it's coming apart or not.
