94 jackaroo auto electrics

a couple of questions if i may.
what happened to your auto and how much was it to repair?
CHEERS

W e spent $4100-00 to get repairs done.
Since its been fixed we seem to have an electrical problem when the vehicle is warm only. the gears seem to stick in drive. and wont change down reverse is ok
this only happens when car has been driven approx 15 ks and you stop and park when you go to start again the check trans light comes on and you only have drive or reverse if you use gears manually in Low or .2. 3. it works. however yesterday
after about 15 ks the warning light ref. over heating in the gearbox came on when using gears manually to get home. We intend taking it back again to the transmission place for the third time They seem to be baffled as well teling us it is electrical fault Once car has cooled down it seems to be back to normal again.
if you have any ideas it would be appreciated

I'd be returning it to the repairer ASAP, especially for the dollars you already paid.

It doesn't sound electrical to me.
