My 2000 MY Grand Cherokee 4.0 auto gearbox cycles in and out

Customer Question

My 2000 MY Grand Cherokee 4.0 auto gearbox cycles in and out of overdrive when I am out on the open road. It used to go into o/drive with a mighty lurch and a drive shattering bang unless I took my foot off the gas at the right time. This stopped about 1500 miles ago and now it wont stay in gear.
I can switch it in and out of overdrive with the gearstick button OK.
It feels like there is a problem with the `lock-in` or something like that.
Is the box repairable or scrap?

Hello Greg,
O/D light is not on nor is it flashing. It only comes on when I press the O/D button on the shift lever.
The `perform service` message on the overhead console sometimes comes on when I first start up then quickly goes out.
I do not have facilities to interrogate fault codes.
Sorry, not v helpful. I`m afraid.
Somebody told me about a clutch in the gearbox, that performs the `lock-in` for the O/D, cracks and fails to perform correctly - could it be this?

I realise we are talking about a 15 year old vehicle here with considerable miles on the clock but I would like to ascertain if it is worth persevering with or to cut my losses and exit left!!
