I have a 2002 dodge ram 4x4 with a 360... I was having some Tranny problems so I took it to a shop had that replace and in the process the computer got messed up.. now the truck won't crank at all.. they tried a 98 computer it cranks the truck but none of the gauges will not work... So when we took it the dodge house they said they put a new computer in it and they said the 2002 computer didn't fix anything and are charging us 500.00 . I don't know what else to do please help...

Are you saying it cranks but won't start?

It runs perfect with new and original computer but no over drive
