Default P0751 1-2 Shift Performance or Stuck Off

I've checked the snapshot which points to the code being set off in 4th gear, ~1800RPM, Engine Load 9%, TPS 12%, Shift Mode : PERF.

The solenoid clicks on and off (i can hear it tick) when doing a component test. Anyone run into this problem? Is this uncommon?

Tranny rebuilt 42k ago, fuddle 3400 with cooler installed 1.5k ago. Tranny fluid was clean before the converter install. Haven't check it since then.

Did u get ur pcm tuned after u got ur stall put in? I once got this code and thought my tranny was going bad but it was shifting fine. I did some reading on it and found out weather or not ur pcm is tuned it will sometimes throw this code. Most people just said to clear the code and turn it off. Hope this helps u.

My car was tuned right after the install and that has been a few months ago.....though only about 1.5k miles since then since i was in an accident.

I've cleared the code and it came back. It shuts itself off after awhile on it's own as well. What in the world does than insinuate?

I would clear mine and would come back on and off every now and then, after I cleared it. I guess the pcm just has to relearn. You have to turn it off with HP tuners. By clearing the code the pcm still thinks u have a stock stall and will think that the tc is slipping and therefore will throw the code, even though it is tuned. The only way to get rid of it is to completely turn it off.
