My dad is a very good mechanic, but doesnt have obd2 diag. He can also tell that there is no first gear. I know theyre not a hot rod by anymeans, but i just got into this 95 short box, short cab, 4.3 automatic with 180 000 kms, from my 94 short box, long cab, 2wd 4.3 automatic with 405 000 kms on it. my old one with more than twice the mileage towed better, had more balls off the line. Also there is only a 4 speed auto in the 95. the 94 had 4 speed auto with torque lock up, whats the deal with that? Hopefully there is someone on here who knows more about this problem than my dad and I. any help would be appreciated. thanks
