E4OD Issue
Hi all, I've got a full size Bronco w/ 107 K miles on it and I'm sure at sometime in the past someone pulled a horse trailer with it. It just started slipping out of first gear back into nuetral and then back again into first gear. It seems to do ok once I get it up to speed (2nd or 3rd gear) but starting out is iffy. What have you found to be the problem when something like this starts happening. Any ideas will be appreciated.

Welcome to FTE and the Big Bronco Forum. We will endeavor to get you the most accurate information we can muster.
My own experiences with the E4OD not withstanding, I would recommend checking fluid condition and level. (Instructions should be stamped into the transmission dipstick). If the fluid is not clear and nearly red/magenta, then it should probably be replaced. Consider spending a few extra dollars to have a shop that has the machine to do so, suck all of the fluid out before they refill it.
I will caution you this. If the transmission has not been serviced with any great regularity, doing a full fluid and filter change can reveal greater problems than you had initially. Not saying it will but, automatics in general, (not just the E4OD) that are not regularly serviced will run for a while with minor problems that are masked by the build up of dirt and crud in the internal workings.

I had a 92 full size bronco with the 5.0L and 4speed auto. Tranny used to shutter when upshifting, usually into overdrive. That's how I knew it was time to change the fluid. Once I changed fluid, shutter would go away. Hope this helps.

Bare minimum would be the factory recommended service intervals. If you tow or use the truck for heavy loads and/or you do a lot of driving in harsh environments like dust, sand, or mud, consider knocking a few thousand miles off the factory recommendations between servicing. I mean, let's face it, compared to our engines, transmissions get overlooked. And its really more because we enjoy the regained power that we feel when we change engine oil or perform a tune-up. With transmission maintenance, it really doesn't give us anything to get excited about. But then, when a transmission fails... yeah, well, then we remember and start to think about all the times we made the engine "all better" and assumed it's power transferring counterpart was "fine back there".
