Hello, I was hauling 3K lb trailer home empty in stop and go traffic and got ses light on. Today checked codes with my predator and got po700tcm code which I did a search on here and found that it is just turning light on for stored codes. Code cleared on its own but now the tranny seems to have a real hard downshift right before it comes to a complete stop. It almost feels like the t/c locking up. The tranny was rebuilt by dealer at 30k miles and now it has 77k. I just was trying to scrape up enough money for new plow now I am worried I have to spend all my money on the tranny. Any advise or info will be greatly appreciated. Predator is always on tow tune and I do not really beat on it to bad. Recently changed fuel filter, tran. filter and fluids.
