I have a 2007 nissan sentra ser spec v 6 speed car. The car is losing power in 5th and 6th gear while pulling the pass out of seattle. Any suggestions on what it could be?

free the engine from the compressor and then remove the plug then first insert the drive belt on the smaller pulley side and after that try inserting the belt on the larger pulley side slowly by rotating the pulley slowly by stretching the belt with a rope

I have the same car and I know there was a TSB for the ECM . I know the ECM issue has cause some cars to stall while driving

SOURCE: fault with 6 speed selector mechanism, suspect

on the expensive side it could be a bent selector fork in the transmission.

on the cheap side it could just be shift linkage that needs adjusting.

are you still under warranty? if so take it to the dealer for a free repair.

Most probably you need to check the clutch

I'm sure it was pulled when they were attempting to locate the FILL hole, not drain the fluid. That mistake has been made many times because the pin looks a lot like a fill plug.
