1995 E-150 Transmission - help please!
We own a 1995 E-150 Conversion van with a 5.0/overdrive transmission. We have a shudder when our van goes into overdrive. We also own another 1995 E-150 parts van that had a 351 W /new rebuilt overdrive transmission with a brand new torque converter. I noticed that the transmissions have different pans on them - ours has a rectangle shallow pan and the other has a longer deeper pan. I didn't realize at the time I took our van and the other transmission into mechanics that the two transmissions were different. I believe ours is an AODE and was told the other is a axode (he said like what is in a heavier truck)?! He had advised me that it would take a lot to change them around and that even then it wouldn't work. We really don't have the money to have ours rebuilt and don't know where to start!
Where do I find information on the transmissions that we have and how do I pinpoint the correct transmission in our van. I was told by other people that our torque converter could be the only fault, but am not sure. The only time we get the shudder is when the van goes into overdrive and depending on the incline, gas and load. It does not slip in any other gears and does not shudder if overdrive is switched off. Please help!

The 302 van has a 4R70W transmission. The 351 van has an E4OD. It would cost a ton of money to switch transmissions and get ir to work. Rebuilding what you have would cost a lot less.
What you probably need to fix your trans is a fluid flush. Find a shop with a flush machine that will use a MERCON V fluid. Most of the time that will fix the shudder when shifting to overdrive. It's very common on the 4R70W transmission.

What you can do also is go to a Ford dealer and buy 4 FL OZ of Motorcraft Additive Friction Modifier and put it in the transmission. This usually works.
It is the same stuff that you put in a LS rear end.

Try fluid change, or the LS additive that Subford advised, then take it step-by-step.

I have a '97 E150 conversion with the 5.4L motor and the E40D tranny. Mine does the exact same thing, only in overdrive. Have a friend local that owns a tranny shop and he says it's some sort of "lock-out" solenoid in the torque converter. I've beeen driving it the way it is for almost two years now and it hasn't gotten any worse. (damned sure hasn't gotten any better either LOL)

There is no "lock-out" solenoid in the torque converter or any solenoid in the torque converter.
There is a solenoid pack above the pan that has a TCC solenoid on it however for the torque converter clutch.
You could have a bad clutch in the torque converter or some other clutch pack causing the problem. Bad sensor information to the PCM can cause this also.

well, like I said, I've been driving it like this for close to 2 yrs now and just got my wires crossed about what he said. But he DID say it was TC related and he DID say something about a solenoid. sorry if I misinformed anyone.

Reviving an OLD thread...similar issues
Need help: 95 E150 Conversion van, auto 5.8L V8 with overdrive
I recently replaced the serp belt and tensioner........Then it became very jerky and slow on upshifts, and the speedo +odo, not working. Fluid levels are fine.
Thinking the VSS, I cannot find anything resembling a VSS (no speedo cables either) coming out of the 20 bolt tranny body. The area where the VSS/speedo cable should be, is covered with a plastic plug.
There is only one connector and sensor on top of there rear diff.
Ideas? Where's the stuff going to the speedo? Anything I could have knocked loose under the airbox and near the belts?
Thanks a bunch.

The PCM operates the transmission and the PCM gets it speed information from the PSOM.

The above is correct. The VSS is located on top of the rearend housing. The sensors do fail from time to time or can get full of metal debris and become non-functional. The VSS signal goes to the PSOM (Programmable Speedometer Odometer Module). If the odometer is black its likely because the PSOM has no power or otherwise failed. As noted above, check the fuse.
