Two Codes- Questions
Alright guys so after getting about 200 miles on my Stroker, my CEL popped back on. I had four codes. Two of which (P0132/P0138) were promptly fixed with new o2 sensors (one of the only things I did not replace).
The other two have me a bit more confused. I have P0705 (TRS malfunction) and P1694 ("buss error"). After reading a few threads on both (thanks CCKEN) , I am going to rebuild/replace the NSS (I never have) for the P0705 and as I have a spare ECM/TCM in the garage, I think I will swap those in before messing with voltages for the P1694. My question is this-
Jeep runs extremely great, shifts fine- no problems. The only problem I do have (have for alooooong time) Is that every other time I turn it on/off, overdrive does or does not work. Turn it on, 75mph is 3600 rpm. Turn it off and back on, 75 is 2500 rpm. I can pull over on the side of the road and make this happen. I have found a few threads about it with no resolutions- I replaced the torque convertor when I did the engine (one of the suggestions). With those two codes now appearing (P0705/P1694) can you guys think of anything (overall problem) that would be causing that problem? Thanks!

Wow so I had no idea the NSS was so expensive. The cheapest I can find it is 195$ on Rock auto. Looks like Ill be rebuilding it!

Make sure all of the electrical contacts are clean related to the NSS before you take out/clean the actual NSS. Check the simple things first!

No ideas huh? I'll report back after replacing the TCM. I have yet to find a thread with a resolution for this.
