Overdrive continued Mk1 GT6.

Hi. At the end of last summer I posted about my OD issue. I have moved house over winter and the car has been in store.

When using the car it will come out of OD when under load - hill or acceleration. This doesn’t usually happen for the first 10 miles or so. 
Today, I took it for a short drive. When I selected reverse, it wouldn’t move, but whined. This was ok later. It then displayed the same symptoms of being in OD and then coming out under load - but I hadn’t selected OD! When I did flick the OD stalk, it clicked.

i was planning to change the oil as a starter. Does today add any more clues to the problem?

Thanks, Jim

No additive in oil I hope? Oil change good start. Then are you certain solenoid is operating everytime and you havent got an intermittent electrical fault? Finally the manual shows the things you can do from underneath like a OD filter clean...

If it's happening on hills you maybe low on oil?

Jim, is this A or J type?

I suspect calling Overdrive Repairs or the other Overdrive specialist may be the way to get an accurate diagnosis, they tend to nail things very accurately.
