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.
