Scotty
I need your help and I would even be happy to bring my van to you to look at. I am a pet transporter and it’s important I don’t have issues with my van. It is throwing a series of f codes and no one tells me what the problem is they just keep wanting to change the transmission. It’s throwing the following codes but seems to run good with a slight hesitation once every so often when I let off the acceleration but I have driven it thousands of miles and the tranny seems fine. It has had miner fuel mileage reduced maybe 2mpg.
can you please tell me what I need. If I need a tranny along with Torque converter that is fine but I can’t really to get into a costly problem and it not be corrected.
Thanks, Cyndi

At that mileage, even though they pretty much have to be almost all highway, you can bet there's a lot wearing out in that vehicle. When is the last time the transmission was serviced? It really should have been done 8 or 10 times by now. The transmission issues should be diagnosed by a transmission expert - not a dealer or chain shop.
