c7hru Posted June 24, 2008 Share Posted June 24, 2008 I have an auto na. whilst driving along i seem to lose power slightly (as if it has shifted up a gear) then regains it again (as if it shifts back down) It is quite hard to explain and doesnt happen very often but just wondered if anyone on here has experienced this / knows what this could be? Thanks Alex Quote Link to comment Share on other sites More sharing options...
georigg Posted June 26, 2008 Share Posted June 26, 2008 Alex, Very many reasons this could happen, you do not say what speed you are doing or what the throttle opening is(are you driving at constant speed(at what speed) accelerating/lifting off etc etc. Check fluid level, colour etc these are really the only checkes you can do yourself. Could be lots of other things from a sticking solenoid in the box to a partially blocked filter mesh. Only real way to diagnose accurately is to take the car to someone with knowledge/experience of auto boxes and let them look at it.

D8MOA Posted June 26, 2008 Share Posted June 26, 2008 do a error code check! could be a faulty speed converter, my friends TTauto had a faulty converter and that used to change gear at the wrong times and back again Quote Link to comment Share on other sites More sharing options...
