I'm running a 2-speed powerglide and the problem is there seems to be too big a difference between 1st gear and drive. I have to manually shift it and I have plenty of power in first but as soon as I go to 2nd the powerband drops off severely and doesn't pick up until I about get to the corner. Is there any such adjustment to be made to correct this? I don't know what rear gear is in this car either. Which is another question. How do I tell what gear I have with no stamp or tag on the outside? Any help would be greatly appreciated.

Does it feel like it is trying to bind up or maybe slipping? You can get a good idea about the rear gear by trying this: Jack up 1 wheel, mark it and the driveshaft. Turn the driveshaft until the wheel has turned exactly 2 revs. The number of turns of the shaft equals the axle ratio.

Unless your rearend is lock in that case jack up both wheels and spin the wheel once.

It does not seem to bind up and it's definetly not slipping. Just when I shift to 2nd the r's drop and it's like I'm waiting for it to pick back up. It also does not downshift automatically- if I shift from park to drive it will just start out in 2nd and I will get walked on. I'm not really worried about shifting it myself I just wonder if there's a way to shorten the gap from 1st to drive.

I also was told that even if I change the rear gear that the difference between 1st and 2nd will still be there only sooner in my shift. Any ideas?

just out of curiosity why can't you just stay in first gear? I drive a fast 5/8 mile track and keep it in first, about 6000 to 6500 rpm. I have a 307 rear with a 1:82 trans gear.

why do you want to shift it anyways? just gear it right in the rear.

I'm with you guys. There is no need to shift. I run it in 1st gear on a 3/8 track with 3.42 gears.

beleive me, if I didn't feel it was neccesary I would'nt. Like I said I don't know what the rear gear is yet and my tach doesn't seem to be working properly right now but it just feels like the motors going to pop if I leave it in first gear the whole time. Sounds like it needs to be shifted halfway down the straights because the r's are so high at that point.

Myself, I'd just do away with that ****py glide and put a TH350 or a manual 3 speed in er'. That way you only need to run in second. Or just pull the cover on the rear and see what it actually is. JMO.

TCI and ryan, it is a locker so I did what you said and with one full revolution of the wheel and the axle turned a tick over 4 1/2 times. Would this compute to say 4.56 rear gear? I guess I will try maybe a 3.42 or something like that and stay in first gear. Do I only have to change the ring and pinion gears?

look man take the time and pull the cover or chunk out and count the gears divide the pinon into the ring and that is your gear in the rear end....... since you dont know if you have a 176 or a 182 in low gear in your glide get the final gear you want to have and put it in the rearend and run in high gear you have less spinning parts in the trans and is easier on equipment

Just get a 3 speed with a mini-clutch. Automatic's need a cooler, that's atleast 4 more possible leak's. I use powerglide's to trade for 3 speed's.
