no, but seeing where you live, it was an easy jump.

i am thinking of buying a 2000 era camaro or mustang to have fun there

Re: Trans failure question...
 

One easy test is with a Line Pressure gauge, Check the pressure in each gear range.

You're correct in your assumption about the Powerglide being easy. I've done 727's, and the Glide takes about half the time.

I broke a 1.76 planetary and it did still lurch when you put it in gear, so a good chance you broke the input. Are you using a stock input shaft? I would upgrade to at least a 300M if so, though a Vasco is best.

If the planetary is good, make sure you check the end play on the gears in it while you're there. I seem to recall there should be .02-.03" between the gear and the planetary housing.

Don't know if you're into the diagnosing before pulling. A third option behind input shaft and planetary breaking is pump gear breaking. Just had a friend's car do this. Pressure test would confirm pump operation if you wanted to know before pulling. Not really needed to diagnose as whatever is broken will be apparent when pulled. Shaft can break and leave a piece in the converter.

Several years ago, i had the drive lugs break off the inside of the inner front pump gear.It resulted in a zero oil pressure situation real fast out of the blue. It was in my Chevelle wagon, same engine/trans combo. When i pull the trans and inspect it,I'll know more.

Re: Trans failure question...
 

Got the trans out of the car. When I drained it and removed the pan, there is a good quantity of aluminum shrapnel in the pan.No large pieces, I don't know if it has an aluminum direct clutch hub, but it's getting a steel one this time around if it needs one. The input shaft doesn't seem to want to come out, but if the splines in the hub failed, that would account for the aluminum debris. The front pump drive lugs were all still there so further disassembly is next. At least now with the new flex plate rule coming in, this would be a good time to change that out as well.

Hi gear clutch hub breakage does not keep low gear and reverse from working.

Re: Trans failure question...
 

What did you find?

Re: Trans failure question...
 

Seemed like a bit of work here, right about the time the trans broke, the flywheel failure in the stocker that resulted in a rule addition happened, so I ordered a TCI flywheel and figured that when it arrived,I would install my other trans I wanted to try which is a 350. The 327 probably would love the extra low gear because it left like a cannon ball with the 2.08 Glide. The input shaft on the Powerglide didn't break, neither did the front pump drive gear lugs. I dropped the pan and found aluminum shrapnel in the pan, but the rest of the trans doesn't seem too contaminated. The flywheel just came today, as did a new Simpson harness,so it's back to work time. I suspect the failure was planetaries since nothing works. We have a trans with Park and four neutrals. Once the car is fixed,I'll open up the Powerglide and I'll know more.
