'99 Thomas dash shifting light not working

Changed out the batteries on the bus today. 1999 Thomas Saf T Liner. Now the "gear" does not display. Usually there is a N then you press D to drive but you cannot press anything now which means I cannot drive it. Bus starts up great and all other dash lights come on. Any ideas what has gone wrong?

I am assuming that your bus has a Allison 3000, since it has the push buttons to shift. Is this a FE or RE?
If it let the engine start, the system sees itself being in neutral. I would start by checking the transmission power, I believe it has a small amperes fuse that power the shift pad also.
it should have a fuse in the electrical panels in the side access.
If you get me the last 7 digits of the vin I can get a wiring diagram

make sure you didnt miss a small wire going to the battery, or it got comnnected to the NEG imnsteasd of POS terminal, etc.. I believe the TCM is powered with an inline fuse directly off of the battery on some of these.. the small wires for accessories are often easy to miss re-connecting..

It's a RE with a Cat 3126b. The last 7 of the VIN are: 1167881
