Hi there, I'm in need of some advice. I own a 89 GQ TB42 lwb automatic. I've been having trouble with the wiring somewhere. Keeps blowing the transmission fuse, putting the car in 3rd gear. Happens as soon as its put into Drive (dont happen in park, reverse,1st or second gear) just wondering if this has happened to anyone else or if it could be anything internally in the gearbox. We've looked over the wiring and cant seem to find the problem. Thankyou in advance
