OD light flashing?? P0781 code

JLElectric · #1 (**permalink**) 12-08-2008, 10:15 AM

the code says 1:2 shift error. Is there a fix or just get a new tranny.

is it slipping, making noise or anything strange ? if it just posted a code, clear it and reset the memory, drive it for a while and see if it comes back.

Just a question, may sound dumb to you guys, but how do you check a code and reset it? I'm aware of codes but do you guys have special equipment?
Thanks

the rpms has to get up there then it goes in gear.no stange noises. superchips tuner does the codes. i have cleared them and after a little driving they come back. it goes in gear just not as fast as usaul. i may just be used to performance mode. i have it on stock now

I had a 1:2 shift error a couple of years ago...unfortunately 2nd gear was completely ripped out and ended up needing a new trans. Your trans might be on its way out, how many miles are on it?

you can do it with an sct tuner, you can go to autozone, advanced, napa parts stores and they have code readers there, normally u can borrow one or just buy one

Usually not, but hopefully its just a code and a real easy (cheap) fix

I"m not 100% positive but I don't the the flashing OD light is just for the trans.

Ok I dont mean to sound stupid but have you checked the tranny fluid? That could cause the slow to change and go in gear issues. I know you probably have , but I just had the thought because I have a tendency to overlook the simple stuff when mine acts up
