truck#1 1995 gmc 3500hd
when i tested the torque contverter lock up by pressing on brake pedel while keeping same speed RPM's raise slightly.
truck#2 1996 gmc 3500hd does NOT do this but at 55 mph when i let off of fuel pedel RPM's will drop to say 1200 RPM's when i apply brake peddle just very lightly(not enough to activate brake pads)RPM's will drop to idel and when i let up the brake pedle the RPM's goes back up.
no mod's on either truck under 20,000 miles on trans. in the 1996.
just over 30,000 on 1995.
should 1996 test the same as 1995?
