It drives well, until it hits 80-100km/hr then it feels like it is surging and doesn't seem to have the power it should. We tried to tow our camper with it but it was a struggle to get it to highway speeds. It felt like it wanted to change gears.
No check engine light or codes present. Not sure about fuel mileage as we haven't had it very long.
It has 216KM on it and the following has been done so far:
Changed spark plugs (AC Delco)
Cleaned Throttle body
New air filter
Changed Transmission fluid
Replaced Shift Solenoids
Diagnostic done, no codes
Back pressure test done for Cat.
Upgraded Tranny to Engine software
One thing we do know is that it needs a new manifold, due to ticking and a visible crack.
Took it to the dealership a few times, no help. Also took it to a local Transmission shop for diagnostic, no codes and was told it had "mushy" shifting
We really have no clue what to do now or where to turn. Any ideas would be greatly appreciated!
have the same problem?
