4L60e problem?? 1st to 2nd and WOT?
Ok guys here's the problem when I take off ( no matter hot or cold) I have to let off the gas in order for it to shift into 2nd after that trans shifts fine unless you floor it then it hits the rev limiter like its in neutral. Ok I changed the filter and fluid ( fluid was a coffee color), also replaced the 1 to 2 solenoid still didn't help. Ok also my speed is way off going 65 the speedo shows 110!!!! Could the speed sensor cause all this?? Or anything else
