Hemi 5.7 p0700 transmission stuck in 3rd gear
 

Wondering how people went about fixing code p0700, goes into park reverse and neutral, but when in drive stays in 3rd gear

Did you end up fixing you issue. Usually the P0700 code is a generic code that there is an issue with Transmission Control System. Is there another code after it?

I had the same issue ended up just being a really weak battery. With all the electronics in these any slight voltage drop will cause havoc.
