The first four gears so you mean you can only shift in low range? Are you able to get it into high range?

[Challenger]

Manual or automated? Your original post seems like you have a range shift problem. But since you checked fuses and solenoids it sounds like you have an automated transmission.

If its automated there should be a code.

The first 5 gears are ok but wont go in the higher ones the range does not make any sound it looks like an electric problem

You may have a bad knob or relay on the trans. Check your uses to.There are schematics and trouble shooting guides online. I found them using google on one I had an issue with. The electric shift was not very popular here.
