67 powerglide dip stick
I noticed on my dads 67 427/390 dip stick under the handle loop there was what looks like a rubber seal that half of it is missing. Also after sitting all winter it leaked about a pint of fluid from the speedo cable area. would the missing seal at the tube cause any problems? Two can it be repaired somehow, and three if not repairable are any passenger car powerglide dip sticks the same?

The 1967 427 Powerglide dipstick, GM #3905447, was unique to Corvettes. GM never offered any repair parts (e.g. seal) for the dipstick. It was SERVICED as an assembly. I don't know if it's possible to repair the dipstick's seal. I doubt that the leak from the speedo area has anything to do with the seal on the dipstick. However, there is also a seal on the dipstick tube. That seal is an o-ring seal and is replaceable. It was last available under GM #6255641.In Appreciation of John Hinckley -

Thanks Joe. I remember the O ring on the bottom of the tube doing assembly of the car. I wasn't sure of the seal on the top was causing any sort of pressure or lack of pressure causing it to leak at the speedo area.Comment

On my 66 PG I had to replace the plastic speedo gear as the shaft had worn and was causing the leak.Comment

Russ the trans was rebuilt for the second time two years ago and all new parts was used for the speedo cable attaching areaComment

Try using some grease or never seize on the the gear shaft as a sealer.Comment

Re: 67 powerglide dip stick
will do. this trans has been a nightmare before it would leak a quart or two. so only leaking a pint over the winter was nice to see.Comment
