Before anyone asks, yes I have read all the stickies, FAQs and searched the forums and interwebs for pertinent information before posting a new thread. I was not able to find a specific solution to my issue, and thought it wise to ask before throwing tons of money at my transmission. So, here we go:
From what I can tell and have read, the CD4E has 4 physical gears and an overdrive. Since I have owned the vehicle, it has never shifted into overdrive.
The O/D off light does not illuminate, even when toggling the O/D switch on the shifter. Shifting behavior also does not change from toggling O/D switch. (Bulb and socket for this light in the instrument cluster is tested working).
History:
Transmission was reportedly replaced with a used one at roughly 110k miles. It then sat for about 6 months with electrical issues (trans shop didn't reconnect ground wire, battery died, etc) at which point I bought it and got it running.
I broke a transmission cooler line while replacing my radiator. Temporary fix with rubber hose didn't hold up, and transmission started slipping and shifting erratically due to loss of fluid. Drained tranny, properly replaced cooler line, filled with fluid and Lucas. Wife reported that it was acting up (actually turned out to be related to a vacuum leak, my mistake for not duplicating the problem), so I drained out a small amount of fluid as to not have too much fluid in trans. Replaced plug and proceeded to crack the transmission case.
(Are we having fun yet?!)
Drained trans fluid completely, degreased and scuffed/sanded area, sealed with JB Marine Weld. Filled trans with fluid. Shifts fine. But still no overdrive.
I'm guessing that I need to start with the O/D switch and work my way from there. Hoping my issue is electrical/electronic as opposed to hydraulic. The lack of any O/D off light leads me to believe this. Any advice or links to relevant information/fixes is appreciated!
