So I have the notorious 2-3rd gear flare shift now. It started about a week ago when I drove on a road trip, parked it at my destination and then when I drove it the next day, 2nd gear is extended. If I baby it, like 1500rpms and no higher, it shifts early (before 25mph) and it continues on in the gears nicely, however any higher rpms and it will just climb until I let off the throttle. I adjusted the front bands, disconnected the batteries and cleaned grounds, turned the key to on position for 30 seconds to let the TTVA calibrate, and nothing is working. I heard that replacing the TTVA has worked for some and I'll do it if anyone thinks it will help. Just really not sure, what else should I look for or am I just needing to go for a rebuild for the tranny?
