Archived wont shift out of first

[GWall]

this happened after i got done doing 4x4 donuts on the pavement couple days ago. it wont shift into second gear unless i take my foot off the throttle, then it shifts into second and the rest of the gears are fine. it had a code 0720, but i unhooked the batteries over night and it went away, but it still wont shift right!!!! somebody help me!!!!i read it could be a low output speed sensor or something??!?!!??!?! thanks

Could it be the TV cable out of adjustment? Do a search for that.

GWall,



P0720 = Trans low output speed sensor rpm, above 15mph



Sensor mounts on the driver side of the overdrive unit. comes out easy with a 1" socket, lose about a cup of fluid. I think the part might be 20 bucks from the dealer. Sometimes you can just take it out and wipe the clutch material/shavings off and reinstall, but for the cost i would just replace it.

This should get your gears back, unless you fried something inside

The sensor is magnetic and shavings will stick to it and cause it to not read right sometimes. I don't know if that would cause your problem though, but it's easy to pull it out and clean it off.
