E4OD no 2-3 shift after rebuild

E4OD no 2-3 shift after rebuild

Postby kquinn8942 » Wed Apr 19, 2017 9:46 am

trans came too me as a bench job, its out of a 96 f350 4wd with 7.3L had convertor codes and high mileage. performed basic rebuild all new fibers, steels and resealed. installed transgo hd-2 kit. I did not replace the solenoid pack as it ohmed out correctly. cust reinstalled trans and said it would not upshift at all. would shift too second if put in manual 2nd. he replaced range switch and now when truck is put in drive it will upshift too 2nd now and lock convertor, cust brought me truck. no codes found with snap on solus scanner. od light is not on or flashing. test drove and seen that ecm is commanding 3rd and 4th shifts but appears too stay in second and lock convertor. ohmed wires too trans from ecm seem good. have power to solenoid pack. im assuming that solenoid a is stuck on venting all the time? can any one confirm this before I pull the trigger and drop pan.

Unplug it do you have 4th?

2-3 shift valve stuck if you have 4th unplugged

if you have 1st unplugged bad solenoid

SSA (solenoid 1) is OFF for 3rd and 4th which means it is ON for 1st and 2nd. So if it is not functioning you will only have 3 & 4 and a 3rd gear start.

SSB (solenoid 2) is off in 1st & 4th. Default with connector unplugged is 4th gear.

SSA SSB
1 ON OFF
2 ON ON
3 OFF ON
4 OFF OFF

If it was stuck on you would have a 2-3 neutral feeling because it would be going back to 1st gear if ssa was stuck on
