As of today, my 1992 ford f-250 has a steady constant transmission leak. in the front of the fly-wheel. Its a manuel 5 speed, and the motor is a 460

Does yours have Electronic Shift on the Fly (ESOF) Operation The electronic shift on the fly (ESOF) system is an electronic shift 4x4 system that allows the operator to choose between two different 4x4 modes as well as 2-wheel drive. The operator can switch between 2WD and 4H mode at speeds up to 88 km/h (55 mph). To engage or disengage 4L range, the vehicle speed must be less than 5 km/h (3 mph), the brake pedal depressed, and the transmission must be in NEUTRAL. The transfer case is equipped with an electromagnetic clutch which is located inside the case. This clutch is used to spin up the front driveline when shifting from 2WD to 4H mode at speed. When the control switch on the instrument panel is turned, the generic electronic module (GEM) recognizes that a shift has been requested and activates the electromagnetic clutch and the relays which power the transfer case shift motor. When the shift motor reaches the desired position, as determined by the contact plate position inputs to the GEM, power to the shift relays and motors will be removed. When the transfer case front and rear output shafts are synchronized, the spring loaded lockup collar mechanically engages the mainshaft hub to the drive sprocket. Finally, the front axle collar is engaged and the electromagnetic clutch is deactivated.

After reading this material I would not think it was the switch . Maybe an input problem to the GEM module .

Feature Inputs:

• 4WD Mode Switch (various resistances; go to Table 1).
• Contact Plate Position Inputs A, B, C, D (grounded when closed, open circuit when open; go to Table 4).
• Output Speed Shaft (OSS) Sensor (Sinusoid Signal: 0.7V-20V, 2.2 Hz/mph).
• Brake Input (battery voltage when brake is depressed, open circuit when not activated).
• Transmission Range Sensor (grounded when transmission is in NEUTRAL, open circuit otherwise).
• Start/Clutch Depressed Input (go to Table 3).
• I would take it and have it check for codes !

You didn't mention if it was 2 or 4 wheel drive so I went with a 2 wheel drive. According to hollander the 5 speed transmaaion fits a ranger (2WD) 1991 - 1994 and a Mazda B3000 1994 only. Hope this helps.....

Check the engine intake and all vacuum hoses for leaks, do this with a can of spray carb cleaner, if you hit a leak the idle speed will change. Repair what you find.

try the coolant.

Transmission Types : Ford E4OD/4R100, 4 Speed, Automatic Transmission
Comments: w/ Shallow Pan = 20 bolt holes 4 speed

Drive Trains : Four Wheel Drive
Transmission Types : Ford C6, 3 Speed, Automatic Transmission =17 bolts 3speed

What does the dash indicator say and does the stick have an od button on it? there is only 1 3 speed for the 460 and only 1 4speed for the 460

Engines:{300, 302, 351w}, {400, 351m, 460}, {6.9L, 7.3L IDI}, {352, 360, 390, ect.}

so you should have the 3 speed acording to the code

Look at the location of the ring gear on the old flywheel and the new flywheel. Soemtimes the gear to installed too far on to the flywheel.

Check that the starter is fully seated, I presume the same starter was used.....If not, compare new and old starter, side by side.

I believe only another 460 motor.

IVE GOT 1989 F250HD XL 7.3 DIESEL 4X4 SUPERCAB. ITS GOT HEAVY DUTY ZF 5 SPEED TRANNY..

depends on the terms and conditions of the powertrain warranty, you should get those from your dealer and reveiw them to see if what he says is correct or call your customer service satisfaction number that should be listed in your warranty phamplet

Its bout the same for all rear wheel. Place a jack to support the transmission, remove the bolts from the mount and frame. If the tranny on a cross member then you should be able to remove the cross member by 4 bolts, then remove the mount from tranny and cross member.
