Transmission 4/3 circuit fault? E4OD

1992 F-350 7.3L Diesel,E4OD Auto, 2WD Just stopped going into 4th/OD. First three gears work like they should, but 3rd is as far as it will go. Code reader says code 62 "Transmission 4/3 circuit fault." What the heck is that? Fluid and filter service about 3 months ago. I replaced the VSS and TPS this year to clear up some other problems. Everything was working great 'till this. TIA

A quick good says... E4OD excessive converter clutch slippage - Transmissions

The code book says that the excessive clutch slippage is for the cars only, that in the trucks code 62 is "Transmission 4/3 circuit fault" I dunno, it's broke either way. Might be time to upgrade to a C6.

Emm... I thought a E4OD was a C6 with an electronic OD

The E4OD is based on the C6. It is a good transmission in the updated form. IIRC, the code 62 can be generated by excessive converter slippage or a delay in the electronics or hydraulics. If the trans has ever been built, especially over the past 5 or 6 years with all the updates, it is likely a slipping converter. If this is the case and the trans works fine otherwise, you may be able to replace the conver and let' er rip. If you have to replace the converter, look for one with the latest HD clutch. I have the LUK in mine which was custom built. It locks a bit hard but gets the job done. There are other causes of a code 62. The electrical can be checked pretty much from the wiring harness if you have an ATSG manual for it. You should be able to find the manual online. I get them from the local parts supplier for about $14 each.
