Hi, as some of may know i have been having issues with the lock out torque converter. It engages and disengages rapidly on the highway.

First i had a reco torque converter fitted, then a brand new Throttle position sensor.
This has been done by an auto specialist who has checked over the system.
Still got the same problem.
The mechanic now has the box apart and says its in really good condition, says it looks like it has recently been rebuilt. (ive not long had the patrol)

Mechanic now thinks it may be electrical: ECU or Road speed sensor.

Firstly, does anyone have any ideas?
And secondly how big a job is it to remove the dash and change the road speed sensor?
How much should a road speed sensor and ECU cost?

Missed out on having the trol on the road for the xmas break
Havent driven it much in the last 3 months!!!! Going CRAZY!!!

Thanks for any help
