disconnect battery is all. then go for it. i don't have the technical data/teference for you on this platform. sorry. it maybe the same as the camry. but i can't be sure the transmissions are the same.















assuming you're refering to the VSS on the trans and not the one in the speedo head.















there is no re-learning curve for the ecu to do on this repair. even if there was, it would do it on it's own.















-----















EDIT,















i should add,















once replaced the CEL/MIL lite should go out. if it returns, the issue is likely in the wiring or connector. disconnection of connector and spraying it with WD-40 might yield some results. i'd actually do that b4 buying one. also, if app, inspect the wires around the trans and up through the engine. there are some wire clips/retainers that can break and let the wire get close to something hot.















once your satisfied the issue is addressed, that is the lite does not come back on, for emmissions tetsing in some areas, you'll need to clear that stored code to pass. remove 15 amp EFI main fuse for 30 secs to do that.















could just as easily disconnect neg battery cable for that amount of time. but that would zero out any cab presets. raido and such. minor realy. but eh....
