wierd electric prob....

ok, here goes. i have some wierd electronic problem. every now and then when i flip my turn signal on, the dash flasher dont work, only on the left side. and, if i drive with my flashers on for an extended period of time (flagging, ect) my ABS light comes on sometimes. and, when driving in drive, in the upper rpm's like where it would normally shift, with flashers on, its like my Torque convertor locks and unlocks. the rpms go up and down. PLUS,,,my speedo wiggles at times.

now, could the ABS light and speedo prob be related to the Speed/abs sensor?

and the rest, who knows?

Check your third brake light and brake lights. Probably have a burned out bulb or a bad ground.

Don't drive your truck with the flashers on until you fix it cause you are not doing your trans any favors!

Check the bulbs and see what issues that fixes first. We can clean up the rest after that. Speedo could be VSS or wiring or PSOM

Only with trailer connected?
Test without the trailer.
The problem could come from it.
Sometimes from a brake controller also.
As Tim stated dont drive it like this. My bet is the CC is out due to this also.
If without trailer check as stated.

Speedo and tach could be from the TC lock/unlocking.

all bulbs are OK. it does it with or without trailer. and, to be safe i took out the TC lockup wire, even though the other side of the switch wasnt connnected. i dont drive it like that. my guess is some sensor? but all bulbs are good, and i think it did it all before TC lockup switch fwiw. thanks

IIRC you just had some trouble with your rear differential. Broken pinion flange or something??
I'll take a WAG and say your tone ring on the ring gear was knocked crooked or bent. No need to open up the case, You can remove the RABS on top the case. Look into the hole and watch the tone ring for side to side movement. Could be the RABS or the wiring too? If you find a lot of metal chips on the RABS......not good.
Is your cruise control working?
