AODE and 4th gear
I notice, when I am doing about 60 or so, if I let of the gas, and push on it, its like the car shifts into gear, the motor winds up a bit and it engages and goes, with OD off, it does not do that, instead, around 50-60mph, it kind of surges and thats the only time it does it.
I recently changed fluid, used valvoline that said it met the mercon v specs, it did the same thing before the trans fluid, I did install a new filter also.
Are there any user-serviceable parts to replace. or adjustments to be made?
Its very uniform in how it does this small slip and engage thing.
