The e40d thread...again...and again..and again
im starting to think that this e40d isnt worth the trouble. but maybe i just need to actually go through the truck like i should and clean it all up.
when placed into drive the transmission is holding 1rst gear.
driving it to the local parts store to see if they had an electrical tester i found that after manually shifting into second and reaching 45 mph, i could then shift back into drive and have 3rd gear until it dropped below 45 mph where it would go directly back to first and hold that until i manualy shifted out of it.
no flashing od light. when placed in 4x4 high the "4x4 low" light comes on and it sticks in 1rst like the rest of the time, untill i shift to 2nd, and then it grabs either 3rd or od in 4x4 andlugs the engine down and downshifts to compensate.
if you get anything out of that.....bravo, because i sir.... am confused
My question is, is there a way to make the trans read off its trouble codes with a flashing dash light like i just got done doing in my 95 jeep? or do i have to go back to the trans shop that rebuilt the transmission and have them fix it?

OK, so just so I'm getting this right...........
When driving on the road with the transfer case in high range, the transmission tends to hold onto the gears for too long. As in, not upshift when it should, but it will shift through all the gears when done manually, so the internals of the tranny seem to be fine. If you still have 1st and 3rd gear, then you do have some ECM control.
When driving in low range, it will upshift too soon, correct? And it will go through all the gears including overdrive.
If I'm off on any of this, point it out.
Unless I'm mistaken, pre 1992 does not have a "flashing overdrive" feature for stored fault codes.
This sounds like a VSS problem. 1991 still has a cable driven speedometer, so any electronic fault in the system will not affect the speedometer reading. Cruise control (if equipped) should in theory be affected.
First thing I would look at is the VSS at the transfer case end of the speedometer cable. Verify that its plugged in, and none of the wires are damaged.

ok so i'v been under my truck now at least five times. every plugin to the transmission is tight and clean, as they have been since the transmission rebuild and they are the only clean thing under the truck, all the wires look good -although i do seem to need to check my rear breaks- the speedo cable into the transfer case is the dirtyest one of the clean ends of everything tied into the tranmission but it is tight fitting and none of the wires seem bad or coroded or anything. is there a simple way to test the sensor?....or i guess is it safe to drive with the transfer case end unplugged or wis trans fluid spray everywhere?

Unplugging the speedpmeter drive cable cable will allow some fluid to come out (and some contaminants to get in). Unplugging the electrical connector at the VSS will not allow any access to the transfer case unles its damaged for some reason.
Only test I know of for the VSS sensor is to take a resistance reading between the two prongs of the sensor. Reading should be between 400 and 900 ohms.
I hate to ask this but have you checked all your fuses?
You could also get a basic code scanner for around $30.

You mentioned trying to read the codes like a jeep. If your truck has the OBD1 system like the jeep you might be able to do that. If the truck has a scanner plug then its an OBD2 system that has to be read with a scanner.
