Last summer I picked up a non-running 1994 Vin K regular cab 4x4 with an E4OD. The engine is not the turbo version according to the engine block number (7.3 U2U1028595). There was evidence of a turbo since there are firewall scorch marks in the paint on passenger side firewall. Not sure what year the motor is, but it does run pretty good.
I have since last year done all the normal maintenance items to get it back roadworthy. Now, my question is the tranny seems to shift thru the gears OK into overdrive. But when I slow down to a near stop, it appears to not want to downshift to a lower gear, unless I come to a complete stop. If I stop completely, and take off, it shifts up thru the gears OK, but seems like it does not want to down shift. What controls all this? I know about the TPS on the injector pump, but I have not touched it. Is the computer module responsible for this? Not sure how the truck knows to down shift when slowing down except for perhaps that speed sensor on the sterling housing. What does the speed sensor actually control? I don't think there are any engine functions associated with the speed sensor. Maybe speedometer/odometer readings and tranny shifting?
Different question but still E4OD related. When taking off from a stop, it shifts OK but kind of sloppy. Then when going into 3rd and 4th gear you hear a grinding sound. My friend says it's the lockup torque converter. We're thinking it's toast. If you ease up thru the gears it will shift OK without any racket, but if you lay into it, boy, it lets you know.
I am inclined to pull the tranny and rebuild it since I have no history on it. maybe my downshift problem is related to all this.
I've rebuilt a couple of trannys years ago, a 904 Torqueflite and a Ford C4 so I am not afraid to tackle it. I found a website www.transmissionbench.com that has parts and a really good video series on rebuilding a E4OD. The videos are free on YouTube if you want to take a look.
There are like 16 videos in the series. The guy's like Mister Rogers rebuilds transmissions!
