Well my truck is a 99 1500 2wd 5.2 with a 46re. I recently installed a reman tranny with reman torque converter. It did great for about 3 months. Now it stays in first all the time. When I unplugged the tranny I get 2nd and 3rd ,sometimes 1st. Any ideas?

 

Any warranty on that trans? If it doesn't go into the gear you tell it to, when you tell it to, with that 8 pin connector unplugged, you have serious issues.
