Im borrowing this truck temporarily. The transmission light has always been constantly on as well with a kick between gear 1&2. just recently the transmission light begins to blink when im accerlerating. once im at a stop it idles a little rough but the light goes to constantly being on. Putting it in neutral ceases it from idling rough. no idea wether i should have it looked at hence im no transimission specialist. Or before it could create a bigger problem. Any offers of advice would be greatly appreciated. Sorry for any mispelling.

Welcome to the site, Alex.

The thing about OBD and OBD2 is that you can't do much without having the codes read and that means taking it to a shop since auto parts stores usually can't pull tranny codes. And that's going to mean a diagnostic fee, usually $100.

First, you can check the fluid level and crawl under the truck and inspect the wiring to the tranny.

Tranny light flashing is a new one on me, though.

Are you sure it's not the check engine light? It sounds like you have a misfire condition. They will often times be mistaken for a transmission problem.

Sorry for the mis-understanding. It is the check engine light that is flashing. Just shows my lack of knowledge with vehicles haha. But yes it does run rougher than it used too. Fluid level is ok. Could possibly be a misfire. I got a decoder myself at dads shop so we'll see what codes it comes up with

A flashing check engine light is almost always a bad misfire. The flashing is telling you to stop driving it before cause damage. You are likely dumping raw fuel into the cats which will cause premature failure and possibly cause a fire.
