Auto Box seems to be slipping.

<< < (6/6)

Budgie:
I'll give the ECU a go and see what happens.
It's been a lot better since I plugged it back in though but it still revs to around 1800 rpm on initial start from warm but it comes back down to tickover much faster now.
I also found 3 of the exhaust manifold bolts on the passenger side were loose (I wondered where the exhaust ticking noise was coming from :roll: ) and that seems to have made it a bit better too.
It doesn't seem to run away so much going down hill as it used too and it seems to give a more even engine breaking as well, it used too serge a bit when it got to around 1500 rpm.
I still need to change the leads, dizzy cap & rotor arm, do the auto box filter and another ATF change. Then it's on to the transfer box, axles and swivels for an oil change.

I think I'll also check the base tickover (by plugging the hose to the stepper motor) as the tamper-proof cap is missing and I know the previous own had problems with high tickover as well. So mybe someone has been in there playing!

Range Rover Blues:
A lot of less weel informed tinkerers have messed about with the base idle screw thinking it controls the running idle speed, so probably best to DIY.
