Down shifting issue, high RPM, lock up maybe, also hard shifting?
So I just bought a 2001 F150 King Ranch 4x4 with a 5.4L. The truck has 225K miles on it and the transmission and I have noticed when ever I am coasting down to a stop the transmission is not down shifting properly.
This is how it works: I am going along (usually over 45) and then when I let off the gas to coast down to a stop light (or brake) I can feel the transmission down shifting very firmly until it gets down to 1st. Then once in first I can come to a complete stop and the RPMS sit at 1200 RPM's and I can feel the drive train really pushing the truck forward. Then after being stopped for 15-20 seconds the trans makes a noticeable thunk and the rpm's drop to around 500 and it feels like it normally should.
Anyone know what the deal is here? The fluid is very brown, but I am afraid to change it as last time I did that to a truck I ended up putting a new trans in 3 weeks later.
