Title: Expected RPM @ 70MPH? (2.0 16v)

Hi All,
Just a quick one, what RPM should I expect at 70 MPH. Just want to be certain that the cars kicking into top gear.

hi there

72mph (true gps, 80mph on the clock) is just short of 3000rpm on my 2.3 estate.

Right, Just been on my private high speed track ::) and got the following results:

MPH (indicated) RPM
70 3800
80 4400
90 5000
100 5500

Should the 2.0 16v engine be revving at these levels at these speeds (O/D not switched off)

hi there

they seem high, but are you cruising at those speeds? ie, back off the throttle. it won't change up into '4th' if your throttle is nearly wide open.

Hi,
Unfortunatly these readings were at cruising speed. Guess I'm looking at a new box :(

It looks as though is not going into 4th/OD with those revs try doing the same speed but with 3rd gear manually engaged.
I would have thought it should be doing about 3000 rpm at 70

hi there

also, are you getting (or had) any flashing from the o/d light on the dash?

you know that the default for the o/d is on. pushing the button (light on in the dash) is off.

Firstly how would I manually engage 3rd. Is this just a case of turning the O/D off (Dash lamp on).
Secondally I'm not getting any flashes from the O/D lamp, the lamp illuminates (switching O/D off) when I push the shifters button, and goes out on the second push of the button.

I sort of raised this issue a few days ago on another thread.

Basically I had a P1761 set (Shift Solenoid #3 functional fault) but after changing this part the fault remains. The more I read into this, the more I thinking new box
