I replaced the 5.3 (old had bad injector and hydro lacked), replaced 4l60 (it was antifreeze in the ATF). 4l60 was rebulbed by "one man shop" (newer used this guy before and no reference, just take a chance).
Relearned crankshaft position sensor (CKP). I drove around, and tyranny doesn't downshift right. I parked AV, reset PCM and now no reverse. 1900rpm on WAT in park. When I switched to "N"- rpm higher on WAT). No codes, no misfire. On WAT in neutral- ATF is dripping from went hose.
Tranny solenoids are switching properly (1-st Gear: 1-2 =ON, 2-3=ON and so on). I se hesitation on PNRD321 indicator- switching from R to P. Handle in park, indicator "R" stays on, release the breaks- "R" goes off. I aske local mechanic for serves- hi is overbooks for next 2 month.
My next steps: 1) replace TPS (I can see TPS is working on the scanner). 2) will check tranny shift/park switch (I have extra one).
Should I bay remanufactured tranny (with dyno tested) and tow the track to bigger shop for repair. Or continue education to practicing DIY on my truck?
