E4OD problems
i have a 92 f250 7.3 4x4 i just bought it the tranny was replaced last fall and it was parked all winter the trans has maybe 400 miles on it i started driving it today and to shift from 1st to 2nd you have to get it up to 2500rpm then let off or it wont shift then once in 2nd if you try to accelerate normaly it will go fine for a second then it is like it pops out of gear it just revs up and wont go but if you let off it kinda bangs back into gear and you can stand on it if you want and its fine what could cause this a sticky valve from sitting? i called the previous owner and it may still be under warranty but if is not what should i look at a new tranny?

Sounds like an electrical issue to me, not sure as to whether the PCM/trans is causing the spikes, or the alternator is going bad and the PCM and trans just suffer from that. Pull the alt and have it tested, next in line would be the TECA relay cause it may be getting sticky and not feeding the PCM properly...

Have you tried resetting the FIPL on the side of the IP.
Sounds like there is a power loss for some reason with the voltage drop.....check the alternator connections. Could also be the regulator (internal) brushes. Do you get a flickering alt light.
Any loss of power would effect the trans it is electronically controlled. Does the light on the shift stalk illuminate dimly.......that could be a bad TECA relay.

Pull and test alternator, I've seen them go bad after just a week of driving - it happens, especially with the high quality (or the lack thereof) of many new auto parts...
Josh is right tho, you got a massive drain somewhere, could very well be the alternator itself, but do test the fuse panel like he says.
The TECA relay is on the driver side fender, tis either attached to the fender under some plastic covers, or tis on the side of a vertical steel plate right next to the fender and again under a plastic cover.

Starting off in 4th gear is more than likely a computer problem, or rather, lack of power to the computer. There is a relay that feeds power to the transmission computer and that can go bad on these trucks.
