Transmission unsure of what gear to select and over revving upon shifts P1614 & P0730
 

Hey guys just an FYI.

If any of you have issues of your transmission shifting funky and feeling like it's basically slipping and getting into the wrong gear check your transmission fluid level. I recently had codes for P1614 - Powertain and P0730 - Incorrect Gear Ratio. After much diagnosing I had my buddy check my fluid level which needs to be done on a lift with the engine running. Seems the transmission was 1-2 quarts low. After topping off and resetting codes all issues were solved and yet to return.

So the big question is.....where did it go?? Must have a leak somewhere.

Someone worked on it previously? Who did the service on it last? Maybe the radiator was replaced and the Trans fluid was never corrected?

yes...the radiator was replaced to due a crack a week prior.

Wow, it's not luck when you keep doing it.

There is your answer. You can talk to the person that did it or if you did it yourself then now you know for next time.
