i have a 92 civic lx just had a tranny put in (salvage part). had the fluid changed it's at the correct level too. whenever i accelerate it shifts at 20mph and jerks and won't shift into 2nd gear until i hit almost 40mph. if a let the accelerator go at 35mph at about 3300rpms it'll shift but hard. i almost have to drive it like a manual.... it also downshifts with a jerk. i'd really appreciate any input on this thanks.
