been having issues with my transmission, sluggish,lots of rpm's to get moving. the problem started after i installed my new monster trans. and my 20" coys. was told by the guy that set up my 12 bolt that it had 273 gears and that my stall(1800-2200 rpm) are not matched, and that going to 373's would fix that. dont know why a 71 pickup would have 273 rearend in it, maybe to P.O. put it in for gas milage, but not what i want. anyway, really soft shifts also. so would this fix my issues? 373's and a shift kit?
