Power glide 1st gear

Adger Smith · 09-16-2021, 03:12 AM

Bob,
When you go from a 1.76 to a 1.96 you may need a converter change to get the most out of it. Because of the gear ratio the converter will usually act a few hundred RPM tighter or it might be sluggish pulling off the 1-2 shift. It just depends on what you have and if the converter/engine likes the gear.
I always test one at a time. Watch your flash off the line and at the gear change. there could be a change.
Good luck.

Thank you Adger.
The overall is 4.57x 1.76=8.043 presently

The lower the ratio, the smaller the input sun gear and the weaker the gear set in general The 1.96 that's popular currently is based on the 1.76 carrier seems to live quite well. Many of the other low ratio gear sets are based on the 1.82 carrier and they can be pretty fragile. I've stopped building anything lower than the 1.96.

How about the 2.08 gear sets?I have one in my Chevelle wit 5.38's for an overall first gear ratio of 11.19 to 1, and my Chevelle wagon has a set of 5.57's for an overall gear ratio of 11.585. Both cars leave well and you go for a long ride in high gear after the up shift.

I always ran a 2.08 with a 5.13 in my 67 Camaro small block stocker. Never had any trouble with the trans though the motor never made much more than 400 hp.
