Okay...looking for some vast expertise here before I dive into my transmission! So summarize, I'm in a 2002 Sentra GXE, 1.8L, automatic transmission, ~165K miles.
Over the last year, during colder months, I've experienced intermittent shifting issues. I've noticed a couple different failure modes:
1) Check engine light comes on and the transmission will not get out of 2nd gear. I restart the car and it works fine. Check the code and I read P0755.
2) Check engine light comes on and system seems to go into a fail-safe mode. Vehicle feels very sluggish during acceleration. I restart the car and it works fine. O/D light flashes for a bit, then goes away. Check the code and I read P0755.
A year ago I thought it was the solenoid pack. I dropped the tranny pan, replaced the solenoid pack, put in new tranny fluid, etc. I did this towards the tail end of winter so afterwards everything worked fine until this winter. The problem came back in what I previously described. But then again, once I restart the car, the tranny works and feels fine.
I have yet to double check all terminals, connectors, etc are getting good contact. Maybe the connector terminals are a bit oxidized causing signal issues. Will double check this over the course of the next few weeks.
I pulled the TSB against this; i.e. Abnormal Shifting of Auto Transaxle (NTB04-35). It states the following:
If you confirm an applied vehicle equipped with an automatic transaxle has ALL of the following conditions:
Has anybody else experienced this? What things have others done to eliminate this issue?
Any assistance would be greatly appreciated! Thanks for your help!

If you confirm an applied vehicle equipped with an automatic transaxle has ALL of the following conditions:
- Abnormal shifting (like: slip, "shift shock", no shift, improper shift timing)
- Transmission fluid is not burnt
- No excessive debris in the oil pan
- The incident is listed as an A/T internal fault as per the Electronic Service Manual (ESM) diagnostic procedure
- DO NOT replace the transaxle assembly.
- INSTEAD, first replace the control valve assembly (valve body) of the incident transmission. Use the latest part number shown in your Nissan Parts Catalog.
