MegaMerc

Of late after driving for 50kms, once pressing the throttle, the car stays in the same gear unlike when 'normal' anything after half throttle the car would drop to its prescribed gear, the car now just revs from what ever gear it is in.

The only time it will drop a gear after the 50km distance, is if i press down to the kickdown switch.

Thought it might be the s/c coolant pump, but the car does go to 250km/h all the time, so im a bit lost could this still be a heatsoak issue or is something else wrong???

try doing the throttle reset to see if this helps.

if not it could be your tcu going bad, or possibly valve body sticking (though this would probably cause jerky gearchanges)
