1997 lesabre electrical transmission problem

Im having problems when I put the car into drive it doesnt seem to start in 1st gear it seems to start in 2nd, this causes the car to accellerate very slowly until it reaches a suitable speed for 2nd gear.
The fuse #8 under the glovebox was blown and has been replaced, once replaced the car ran fine. Unfortunately the fuse blew again and the problem persists, I am assuming the problem is caused by an electrical component malfunctioning. What does fuse #8 (powertrain fuse) control, what does it go into and how do I find out what is the problematic electronical component?

Welcome to AF, this powers up the trans solenoids so the trans is in "limp mode". There is no quick answer for this, pinched harness somewhere, shorted solenoid in the trans, a wiring diagram isolating that circuit is required to track this. If you had recent work done under the hood or car, it may be related.

Thanks for the quick response.
I am thinking it may be a solenoid, when the fuse was replaced it took about 30 mins of driving before it blew again. I think this factors out a pinched wire but I will have to experiment some more.
