So recently did a transmission fluid & filter change and topped it off with the Toyota Type-IV ATF, was having issues with drive and it worked for a second after I took it out for a light test drive around the block, but it felt as if it were slipping, it would drive but if I adding any gas it would slip, eventually got to a point to were reverse is the only working gear, curious to see if this is a solenoid problem, also threw a P0500 code so I (think) I can rule out the ECU/ECM being faulty. But I’ve also hear could be a shift linkage problem ask well.

 

Might get more responses if you post to this forum here.
