Re: Rear gear and transmission ratios of 16 valve 740 700 1989

posted by  someone claiming to be Paul Bente on  Wed Nov 1 15:20 CST 2000 [RELATED]

According to Paul Grimshaw's book "The Volvo Performance Handbook" the AW72 transmission on 700's and 900's with the B234 16-valve motor has ratios of 2.83, 1.49, 1.00, and 0.73 (OD) driving a 4.10 ratio rear. The rear is a Dana 30 used in lots of Chrysler Corp cars (Mopar) and Jeeps. There are lots of aftermarket gear sets available as well as limited slip and various locker options as well. Check out a copy of Mopar Action magazine for ads and ideas. The AW72L on my '91 940 has a lock-up torque converter - don't know about the earlier 700s. If you use the AW72 with your turbo be aware that the stall speed is higher than the AW71 2450 vs 2000. Would help drag racing but might not be as drivable around town.

Good luck with your swap.
