Not engaging 4th gear, P0744?
So I have and been working on a '08 Versa Hatchback 4 speed Auto. This car had one CEL code in the beginning which was a P0420 for the cat, which ended up getting replaced. I did a fluid change for both oil and transmission. It also was leaking around the transmission oil pan so I ended up changing the gasket it out also. Drove it around a bit, no codes, but I did notice that it wouldn't go into 4th gear, o/d wasn't engaged(light was off). I would be doing 60mph at roughly 4k-5k rpm and the engine would be roaring. I was previously a Nissan lube tech, so I'm sure I've done the fluid change properly. So I decide to check if there are any pending codes and there beholds, P0744 - Torque Converter Clutch Circuit Intermittent. After reading it moves over and turns into a CEL. Service manuals says it's a mechanical issue than a electrical issue. So I set the car in the garage for a copule days, I start the car and all of a sudden the code disappears. I got all stoked and thought it might've magically fixed itself. I go for a drive and its still not engaging fourth gear. So.....fuck. No check CEL, no pending codes. I assume it's a bad shift solenoid or a bad torque converter, but shouldn't it throw a code? Unless I need a OBD2 the reads tranny codes? What do yall think?
- Did basic fluid change, replaced tranny oil pan gasket
- Not engaging 4th gear
- Check code P0744, CEL comes up
- Days later, CEL is gone
- New tranny?
P.S. when the car is on the "on" position(engine off) as i step on the petal I think the throttle body or something is making a buzzing noise.
