starting troubles and tranny problems
 

i own a 1991 ford f 150 and for some odd reason bout a month ago i started having troubles with it starting so id have to pop the hood get out and jump the solenoid then the other problem is when i try to slam get going by slamming the throttle it starts slippng on me so i have to ease into it every where i go. so if any of yall can help me out that would be greatly appreciated

First questions would be..

Does it crank in neutral? just not in park?
How many miles on the truck/trans?
Trans level checked and full?
