1997 F-53 E4OD Transmission Problem
On my latest trip my E4OD went into Limp Home Mode for no apparent reason. Comming out of the Verde Mesa NP headed for home in CA, I stopped for the night with everything working. The next morning the transmission would not get past 2nd gear. The shifts from 1st to 2nd were smooth and there didn't seem to be a overdrive gear either.
The MH is equipped with a Gear Vendor Under/OverDrive so I was able to travel at 50mph at 3400rpm for the remainer of the trip. The RV also has a Banks TransCommander which modifies the shift points. I checked the fluid and added a half quart that first day. The weather was cool too cold all the way.
Is it possible for the TransCmmander to cause the the LHM condition or do I need to head for a transmission repair shop?
Thanks

unplug the trans commander and have the factory harness plugged it. This transmission adds clutchs for each upshift and does not release any. Usually a flashing OD light will tell you that there is a transmission issue. Possible transmission range sensor issue also. It may need diagnosed professionally but at least you can plug the transmission into the factory harness.

When mine did exactly that (only I had violent shifts) it was my VSS. Same deal, it worked/shifted fine on my way home, next morning after recovering it, left to take it to storage and had the OD light flashing and the sifting issues. Ended up being a bad ZF brake assembly, it had ran dry on trans fluid and melted the VSS drive/driven hears which are plastic.

Question...I have the same year F-53 and my OD light is flashing now too...will my OBD-I scan tool pick up transmission codes or is this something that requires a Trans specific scanner? Thanks!

If your chassis is a 460 CI and E4OD equip F53, you will need a EEC IV diagnostic tool. If you have a V10 with a 4R100, a OBD II scan tool will be needed.

That looks like it would work. The transmission codes should be passed through that scan tool.

The code reader to get is this one in the link below as it will read out the engine and transmission codes for you.
A scanner will also read out the voltage readings and their values of the sensors but is not necessary for reading the transmission or engine codes. A scanner will also cost a whole lot more than a code read.
Get the 3145 code reader below at any O'Reilly auto parts or at the link below.

Thanks Subford...I posted the wrong link in this thread....the code reader I have is the one you recommend...which makes sense because you recommended it to me on a backfire post I had back in 2012!
I'll be posting my findings this weekend when I get a chance to work on her.
