It's a 2009 pathfinder s v6 4x4 , it had coolant contamination it kept blowing the at/ecu fuse and would go into limp mode then not start until I put a new fuse in, so we completed the radiator bypass, flushed trans, installed a used valve body & tcm (off eBay from a reputable seller) with all solenoids (was told it didn't need to be reprogrammed) it starts shifts between gears ( only coasts forward in drive and coasts backward in reverse) but when I step on the gas it only fluctuates between 1500-1800 rpms flat to the floor. (*then I purchased another used valvebody/tcm from another seller and it did the same exact thing no acceleration. I've changed the pedal position sensor- that did not fix it, I've done the relearn process -that didn't work either. The only issue is it doesn't accelerate at all, it only coasts with barely any throttle response. I had it towed to my local Nissan dealer and "they said since I installed used parts the reprogram didnt work and they'd need to install a new blank tcm for $1600 , feeling like they gave me the run around I just had it towed back to my house.. please any help is greatly appreciated I love my pf and need it driveable! -ahhhhhhhh
