Chrysler 300 PRNDL all lights indicated
 

Hello ,
My chrysler 300 year 2007 2.7 v6 had an engine issue and i got it checked with the mechanic and he replaced the engine on it. After the engine replaced the transmission is acting weird it looks like its in "limp mode" only park, reverse, neutral and 2nd gear work no overdrive range. all the lights on the PRNDL are illuminated and when i put it in reverse the reverse lamps dont light up. i went to a transmission shop they say its some electrical issue. i am thinking its the TRS sensor in the value body. could that be the problem or something else. please help me thanks i just joined the form cheers and happy new year.

transmission relearn maybe?
