'98 1500 with the 318. The transmission shifts into overdrive, however the overdrive on/off button on the shift lever doesn't do anything. The light on the dash doesn't light up, and it doesn't kick it out of overdrive.

Is this a simple matter of pulling the dash apart and re-connecting a wire, or is there a chance that it's something else??

 

Also, my reverse lights don't come on unless I hold the shifter a little bit higher than where it normally rests. Any ideas?

 

i just going to guess - that the o/d button on the end shift lever is broken. i doubt that you need to tear apart the whole dash. download the 2001 service manual in the DIY merry christmas thread. most of it applies to your 98. i think you just pop it off and replace it. ??

backup lights - well i/m 0 for 2, don't know whether that switch is internal to trans or external on the linkage, but the service manual will describe it.
