ok... swapped my 249 for a 242 ina 93 GC 5.2 L, auto., swap went actually easier than I thought. Everything hooked up, all fluids full and new. Switched over speedo assembly, 4WD indicator switch. BUT.... now my speedo doesn't work and i can't get into overdrive. I switched the entire speedo assembly, including the gear(black one), thought I put in back in the same way as on original. Do I need to switch to the red gear that was on the 242 originally? I was thinking indexing the speedo, but didn't think that would have any thing to do with the tranny not going into overdrive. Any thoughts or help greatly appreciated!! Thanks to Swampboy for the (mostly) easy swap!! thanks

Try indexing the gear it might work..

As for the overdrive ..Its actually possible that your computer is not allowing you to shift because of the signal from the speedo..

But more likely that you unplugged something under the vehicle when you where pulling the t case.. Check carefully...

And make surethe OD off button isnt pushed.. as silly as it sounds I know a guy who had lots of trouble with his tranny.. Even brought it to 2 different tranny shops then came over and showed it to me.. He almost crapped himself when he found out he had been driving around for 3 months with the over drive switch pushed in...

Sometimes its just the simplest thing.. Mr. Green

I doubt thats your case but .

So back to the original turn it 180* and see what happens...
Unless you include the sawzall work..

if you unplugged something on accident, the place to look is a wire plug coming out of the top of your transmission oil pan. It should be next to some shifting rods or something if I remember. Anyway, the overdrive solinoid is inside your tranny oil pan and thats where your comp plugs into it.
