97 dodge ram stuck in second gear!!!!

On my way home my truck would not switch out of second gear, after a while of reving and puting it in 1st and 2nd manually it started working fine then happened again. I replaced filter and fluid, what should i try now? Any help is appreciated.

is the check engine light on?

yes i went a little bit ago and had it read and a TCC torque converter clutch code came up. On way home, found out after getting to 2nd, to get to third, put it in nuetral and back in drive and switches okay but not like it use to be. A lot less smoother i guess. But im not sure if its the TCC i need to replace or something in converter. Any ideas?

check all fuses, then check wiring on transmission for melts or bare wire grounding out.

clear the check engine codes first and then rescan
post codes here

I bought a used trany and had a friend put it in for 900 all together! its been running great! thanks
