I just put in a E4od. This is the second time the same thing happened. After it was in, I drove it down the road, stopped, went to put it in reverse and nothing. No gears after that. For a while it wouldn't even restart. I will run now, but no gears. I put this one in, because the same thing happened a couple weeks ago when I put the transmission in, so I thought it was bad. Put another in and the same thing again. Anyone know what it could be?

Did you check to make sure that the transmission shifting follows what it says on the shift indicator? How about putting your truck vitals in your signature file. It will help in responding to your questions.
Good luck,

No vehicle movement
• Low one-way clutch overheating the ball does not move freely.
• Transmission fluid overheated and smells “burnt" Does it smell ok and is it @ proper level?
Shift Indicator Cable
Remove the four screws from the lower steering column shroud. Remove the lower steering column shroud.
Rotate gearshift lever (7210) clockwise until it bottoms out in first gear.
Rotate gearshift lever counterclockwise three detents (overdrive position).
Hang a three-pound weight on the gearshift lever.

this is from my 96's Service Manual; is basically same as your year
Transmission Installation
Before installing transmission, check wiring harness for damage. Check connectors for electrical integrity (terminal condition, corrosion, contamination and seal integrity). Repair or replace as required.
Place transmission onto Rotunda E4OD Transmission Jack Adapter 014-00763 or equivalent.
install transfer case to transmission. Refer to Section 07-07A, Section 07-07B or Section 07-07C. On F-Super Duty Models, install transmission-mounted parking brake. Refer to Section 06-05 in the Body, Chassis Manual.
Check condition of transmission fluid filler tube O-ring, replace if damaged. Install fluid filler tube.
Rotate torque converter studs to align with flywheel mounting holes.
CAUTION: Prior to installation of the transmission assembly, the torque converter pilot hub must be properly lubricated.
Lubricate torque converter pilot hub with Ford Multi-Purpose Grease DOAZ-19584-AA or equivalent, meeting Ford specification ESA-M1C45-A.
Raise transmission into position while watching for any obstructions. Do not allow torque converter drive flats to disengage from pump gear. Rubber converter drain plug cover may be removed to aid in the alignment of the converter studs. Use care not to damage theflywheel (6375) and converter pilot. The torque converter (7902) must rest squarely against theflywheel. This indicates that the torque converter pilot is not binding in the engine crankshaft (6303).
Install transmission-to-engine bolts. Alternately snug-up bolts. ... alternately tighten bolts to 52-71 Nm (38-52 lb-ft). .
NOTE: Case connector fitting should be held with wrench to prevent it from moving when tightening tube nut.
Install transmission fluid cooler tubes to transmission fittings. Tighten to 16-24 Nm (12-18 lb-ft) on all applications using 5/16-inch OD fluid cooler tube or to 23.3-31.7 Nm (17-24.4 lb-ft) on all applications using 3/8-inch OD fluid cooler tube.
Install transmission support crossmember (6A023) and transmission retaining bolts. Make sure that wiring harness is properly routed
Remove safety strap and universal high lift transmission jack.
Rotate crankshaft using a 15/16-inch socket on front pulley bolt to gain access to torque converter studs. Install new converter stud nuts using a 9/16-inch socket. Tighten to 34-46 Nm (25-34 lb-ft).
Install starter motor (11001). Refer to Section 03-06A or Section 03-06B.
Install rear engine plate cover and lower dust cover bolts (or screws). Tighten all bolts to 18-23 Nm (13-17 lb-ft).
Completely seat solenoid body connector into solenoid body assembly receptacle by pushing on the top of the connector. An audible click indicates full contact. Verify connection by pulling on harness.
Solenoid Body Connector Seating

Install transmission heat shield (7A434) with off-set bending inward. Tighten to 9-12 Nm (77-104 lb-in).
install new wire harness locators into transmission support crossmember
Install new wire harness locator into extension housing wire bracket.
Install four-wheel drive switch connector, if equipped.
Connect transfer case shift linkage, if equipped. Refer to Section 07-07B.
Install Transmission Range (TR) sensor connector. An audible click indicates full connection.
Install shift cable, or linkage on F-Super Duty and Motorhome vehicles. Refer to Section 07-05.
Install parking brake (F-Super Duty). Refer to Section 06-05 in the Body, Chassis Manual.
CAUTION: Be careful not to nick or damage extension housing seal during driveshaft installation.
Prior to installation, lightly coat slip yoke with High Temperature 4x4 Front Axle and Wheel Bearing Grease E8TZ-19590-A or equivalent meeting Ford specification ESA-M1C198-A.
Install rear driveshaft. Refer to Section 05-01.
On 4x4 models only, install front driveshaft. Refer to Section 05-01.
Remove safety stands and lower vehicle.
NOTE: When the battery has been disconnected and reconnected, some abnormal drive symptoms may occur while the powertrain control module (PCM) (12A650) relearns its adaptive strategy. The vehicle may need to be driven 16 km (10 miles) or more to relearn the strategy.
Connect battery ground cable (14301).
Fill the transmission to the proper level with Motorcraft MERCON® Multi-Purpose Automatic Transmission Fluid XT-2-QDX or MERCON® equivalent. Refer to Fluid Capacity chart under Specifications.
