This morning was on my way to work, and all of a sudden the car felt like it stalled, the transmission light came on, and felt like it went into limp mode. The car wouldnt drive anymore. It almost felt as the battery died because the ac got real weak. So, I put my hazards on, and turned it off, waited a minute or so turned it back on, and it started driving fine. Altough, the transmission light was still on. I parked it at work, came out about a few hours later came out and left work and no tranny light. Drove for about 5 min and the check engine light would flicker on a few times and go away as the car felt it would loose a little bit of power. Took it to a local tranny guy and he found no codes, battery was fine, and no fluid leaking. What could I be looking at here?
