Also a rich mixture from a bad temp sensor could do it.
Temp sensor checked with ohmmeter.
Bad ones usually go 0 or infinite.

Usually when you loose reverse in this transmission it it because the reaction shell strips or breaks do to high line pressure caused by a P01870 code being pressent.Another common cause is the needle bearing on the input drum/shaft breaks up and the pieces get lodged in the reverse input drum and keep those clutches from applying.Long and short is there is no simple fix,adjustment,or sensor that will keep you from having reverse.It is time for major transmission repair.Let me know if I can help in anyway.Thanks David@FIXYA

Sounds like you either have a bad headlight switch or a bad relay under the hood. Also you might want to try turning the lights on for a minute without the motor running,if they work with motor off then its probably the headlight switch.

Change your TPS Throttle positioning sensor it cost about 20-30$ Good Luck!!!
