E4OD Case Swap
I have an E4OD behind my 434 motor. The trans is an 89 to 94 460/7.5L trans. I am having problems with shifting. It doesn't go into 1st when I shift from neutral, and sometimes when I stop for a traffic signal.
If I manually put the trans into second, then back into drive it shifts correctly.
It might need a new valve body, but I want to continue driving it for a while.
I am thinking about buying a rebuildable core, and getting it rebuilt with all opgrades. I'll swap it later.
If I can purchase a 460/7.5 case, and a gas or diesel trans, can I swap the case?
Can I get a new valve body installed without removing the trans?

Any 460/7.5L case will swap with another 460/7.5L case. The innerds (how's that for a technical term) will swap from any E4OD to any E4OD case. Was that what you're asking?
Valve bodies can be swapped by removing the pan with the trans in place.
Have you verified that the shift solenoids are going to the first gear state when you don't get the downshift?

I am going to splice a wire to the S1 Solenoid wire, so I can verify that the controller does energize the S1 Solenoid, when I shift from Neutral to Drive. Then verify that the trans is not in 1st gear.
Is there a test breakout for the Solenoid Connector available?
How difficult is it to swap a 4x4 trans to a 2WD? I have a 2WD Extension Housing.

I don't know if there is a breakout available.
Swapping a 4x4 to 4x2 involves changing the output shaft. That requires taking EVERYTHING out of the transmission, swapping the output shafts, and putting it all back together.

If I am doing a complete rebuild & swapping cases, changing the output shaft should not be an issue.

I spliced a wire onto S1 Solenoid wire, and measured about 8.9 Volts in all shift positions. I assume that's normal when the solenoid is energized. I didn't drive it to see if S1 turns off in 3rd. The trans does go into 3rd.
If I shift from neutral to drive the Range Sensor indicates Drive, but sometimes the trans is in Neutral, until I bump the shifter. Then I can feel it going into gear.
Could I have a bad detent?
Where are the detents? Are they in the Range Selector Switch, or in the trans?

The detents are in the trans. You can see them with the pan off. The TRS can be adjusted, too. With the trans in neutral there are two marks that must be aligned.

Mark,
I can't align the marks with the trans in neutral & get the mounting screws to mate with the trans. The marks are a little misaligned with the range selector all the way to one side of the slots.

Mark,
This is the transmission that I had trouble with the VSS. I bought it without an Extension Housing, then wound up with a 4R100 housing, and an 18 tooth reluncance wheel. It was supposed to be a '94 E4OD, but the E4OD housing wouldn't fit over the 18 tooth reluctance wheel.
It's possible that I need a 4R100 MLPS. I would also need a mating connector, but the Baumann Controller will work with either type MLPS.

I bought a MLPS for a '97 with an E4OD. The part fits and the neutral marks line up, but the body of the unit is below the trans oil pan & the connector faces forward toward the motor.
Is this the normal mounting position for this MLPS?
I know I'll need an 11 pin connector & add wires to the harness, but the Baumann controller will work with the digital gear information.

Mark,
I'm still using the old MLPS. When I shift from Neutral to Drive, the controller display indicates Drive, but the trans is still in neutral. When I shift from 2nd to Drive the controller indicates Drive, and the trans is in drive. The controller uses the MLPS voltage to determine the correct gear.
I think that this could be an internal transmission problem.
