Hi

My P38a 4.0 seems to be stuck in sports mode, ratios & revs don't vary whether I press "sport" button or not. Is there a relay, fuse or something that could cause this?

Cheers.
 
The result is mine never reaches top gear at 30mph whether sport mode is selected or not and uses more fuel as a result.

Mines a diesel and it doesn't always reach top gear at 30mph. That does not necessarily mean it will use more fuel as torque converter lock up does not occur until around 50mph and most of the losses are due to torque converter slip at lower speeds. Indeed holding a lower ratio will actually reduce torque converter slip up to a point. So is it really not reaching top gear, or are you confusing top gear with torque converter lock up by any chance?
 
i think mine only goes to 4th on the motorway!! the torq converter, as i understand it, effectively doubles the gear ratios. on light of this, the car in 3rd is in 6th. the only way i can tell is revs dropping. i'll count em on my way to work and let you know in the morning

Mine will uaually go into 4th at 38mph approx, below this I can shift from D to 3 and the revs don't change hence I know it's not in top.
 
if in doubt with any autobox, change t fluid and t filter, i had this problem changed t fluid , problem solved. now you must flush t box and t torque converter by , filling 2 correct level, start t car cycle through t gears and return 2 neutral. now drain again and repeat process twice more, seems every change only really removes about 30-35 % of fluid.

Now that might make sense as I serviced the box and TC and it would only take about 4l of fluid, no way near the 9.7l it states in the hand book & rave.

I'll give it another go at the weekend.

Cheers.
