CHEVROLET OTHER ENGINE PROBLEM

1996 Chevrolet Other • 214,000 miles

I have a 1996 Chevrolet P30 UCBC Step Van with a 5.7L 350 engine.
It has sat for a year without starting. Everything was fine when it was parked. While it sat a huge tree limb fell on the hood and bent the frame. Luckily it didn't appear to break anything other then the hood assembly and bending the frame. No radiator leaks or anything.
The truck before it was parked had an oil leak, suspected to be coming from the oil pan. I picked the van up 2 days ago, dumped 5 ounces of pure acetone into the tank which had around 24 gallons in it and added another 15 gallons of fresh gas, as well as some chevron techon fuel additive. I checked all of my fluid replaced my battery and it started right up, I warmed it up for a good 15 minutes to get everything flowing and loosened up, then it was time to drive it 75 miles home. The (engine) ran awesome, and it should it has been well maintained and I have always ran synthetic fluids in every place that I can. It has a K& N air filter, and new plugs. I've always used oem and ac delco parts. When I hit the road the transmission did not want to stay engage, it would engage, pick up speed, pop back out, the engine would rev loud and then it would jerk back in, this was a constant problem and I was not able to exceed 45mph. I double checked the trans fluid everything was fine. It would drive fine in the city though (low speed, low rpms) When I got it home I pulled the engine cover and started my investigation. I found an oil pressure sensor is the real source of the leak. It is shooting oil right out into the electrical connector and it is dripping off of the transmission and onto the oil pan and exhaust. Other than this one problem I have no idea what the issue could possibly be. My name is John and I am desperate for information. I can be reached via phone @ 386-212-2584 or e-mail Dawg_27@hotmail. Com Thank you for your time and any help you can provide!

First don't ever put your phone number in some place like this becaue yo neverknow what idiot will call you up. Have this scanned for codes. Install a new oil pressure switch and then uses dome brake clean/choke cleaner to get the oil off on thetrans. Clean teh connector on the trans with same then plug it in an dsee if it does the same thing if it does have a trans guy scan it as it can be an internal problem or and electrical one. But my guess is that the oil has screwed up the sending and recieving part through the connector. If not it will have to be scanned

It won't let me edit the question. However I need to add that the speedometer moved while in neutral when I rev the engine. Also that the speedometer would not move past 35mph while driving, even when doing 55mph.

Then you may need a speed senosr butscan it for codes first.
