This ring gear is no good. Furthermore, the lever that engages this ring gear[located in the case] may not be in very good shape either, so you need to check it out.

Yes that is correct. Check out the end that makes contact with the ring gear. It may look a lot like the ring gear.

Check it out good, so your car will hold in park.

2nd Opinion

Ok I got a new ring gear. I just got the tranny back from the shop, had them install new bushing. I asked about the parking paw, the guy told me it should be fine that i really didn't need to replace it. Only if I wanted to, so I took a couple of pictures so you guys can have a look, So what do you think.

Just compare it to a "GOOD" one and you'll quickly decide to replace it too; the tangs are too rounded.

Yeah I probably would but is this one good to use or not and are they easy to change out or PITA and how do you do it, the manual/Video I have don't say anything about how to do it just to change it if it's bad.

Is'nt the parking pawl just held in the case by a pin that's retained by a small c-clip? Been a long time since I did one (powerglide racer). Seemed to me the first trans core I got was a parked car that got hit and the case was cracked internally by the parking pawl mechanism being stressed. Only knew it after tearing the thing down. They replace the whole trans and I had to start over. Been using powerglides since. BUTCH.

Ok so how do you replace it, there's a plug that cover the pin that holds it in. Do I remove the cover looks like a small freeze plug or something then how do you remove the pin that holds the pawl in.

Ok you guys were right so I went out and bought a new parking Pawl. Yeah I can see the difference. ( I'm starting to hate you guys making me do all this extra work J/K)

Here are some pictures but i still need to figure out how to change it.

it is easy on the bench.. slide the pawl forward on the pin.

Push it at an angle with a punch so it binds on the shaft(pin) , then whack the punch with a hammer.

Couple of whacks will dislodge the cup plug with the pin.

It may take a time or 2 to get the pawl to force the pin out.

clear as mud , I hope.

Thanks Crosley

Yeah!! I got a chance to try it last night and got it out, the only thing I did different was to use an old pair of vise grip to hold onto the pawl and whack a couple of times and bam off it came. I did nick the pin but i going to grind it down and smooth it out, looks like it shouldn't be a problem.

Thanks to all who replied
