Overdrive issue

AW4 is acting up in overdrive:

-won't accelerate well
-wont downshift to accelerate unless you mash the skinny pedal
-when trying to smoothly accel, the engine rpm are going up, but the sound of the engine is bogging down

-vibe only in overdrive
-speed and rpm is not relevent

-Just an overall loss in power,
-I have to be going like mach 2 to even shift into it
-tire size and gearing not relevent

I know I have a cracked manifold, but surely that can't be to signifigant can it? (exhaust also ends before rear axle)

All other gears are fine.

Impossible. Either you aren't listening to engine sounds, or if this is actually taking pklace your tachometer is FUBAR.

Yup. I wrote that all wrong- gas pedal going down, RPM's stay the same, sounds like it bogging. -again only in overdrive.

TPS is good to.
