2003 Chev Venture has no 3rd gear. When the scan tool says "Gear: 3" it free revs and acts as if it was put into neutral.

There are no codes what so ever.

Every one of these I've ever dealt with before always set a code. That's the part that has me stumped.

Any ideas??? Thank you!

What scan tool are you using?

Does it free rev when you put it into 3rd manually?

If you put it in 1st, accelerate up, let off gas, does it engine brake?
