Im not sure which transmission I have to do think its the 4 spd od its on in a 98 c3500. It shifts hard from 1st to 2nd on sometimes on occasion if under a pull from 2nd into 3rd but very rare have chked fluid & it smells & looks burnt also the transmission does have a leak somewhere not a huge one but a leak none the less could it b the clutches slipping from oil & trans leaks or could it b something major inside the trans im eventually going to do a performance build on the motor & trans but waiting til.i have the money just looking for options for now to keep from ruining the trans all together
