Yes perfectly all right for top gear (D). What you're not getting is the Overdrive. Button is on the gearstick. If your overdrive is NOT engaged, there should be a yellow warning light on the centre console up towards the dash.

Try switching the switch on the gear lever. The O/D will only come in when the engine is warmed up a little and the speed is over 36 mph.

You will then feel 2 changes to the revs. One change is the lock-up converter activating and the other is the OD gear kicking in.

Revs/MPH for OD enaged is approx 2750 rpm @ 70 mph.

Let us know how you get on.... Smile

yes you are right the overdrive was off will test drive in the morning.
don,t know what i would without you chaps. another thing you might be able to help me with is how to disconnect the reversing buzzer as i want to fit reversing sensors and two buzzers could be very confusing.
again thanks spitzdog
