If your 1997 Chevy diesel will not shift into overdrive, you might have an issue with a transmission sensor. Some of these vehicles have several sensors that must engage in order to shift.
if overdrive light is flashing , take your vehicle to a transmission shop that light indicates a problem in the transmission do not ignore it to long or you will be calling a wreckr to come tow your vehicle as the transmission will quit i been there lol
Mine is getting 10ish without the overdrive engaging, so I'd guess it would do better with overdrive.
What about the overdrive needs reset? If it isn't working, then you need to have the computer checked for codes, you need to check trans fluid. etc...
if the speedo is also not working it could be a vss problem or an issue with the gear or square shaft where speedometer hooks to tranny/ if speedo works just no overdrive there is a temp sensor on the tranny that can keep od from working or may be wiring issue with factory od on/off switch
A gas engine produces its own vacuum, where a diesel engine has to have vacuum artificially produced. Your transmission problem doesn't sound like a vacuum problem. Have you checked the fluid level? When was the last time you changed the transmission fluid filter?
It does not mix under normal conditions. If this is happening with your diesel engine you may have engine trouble.

I had the same problem on a Peugeot 405 Turbo Diesel. The problem turned out to be the water-in-diesel sensor itself - so I have ignored it for the last 5 years! It is probably the water-in-diesel sensor which is at fault. I have had the same problem for over 5 years on a 405 turbo diesel - so I have ignored it.
you can put out a flame in it no problem
