115 at 6200 rpm 373 sounds like third gear , . But note 1 most 4l60e trans can not do a FT OD unless reprogramed in the PCM to do so , And lockup is never allowed unless programed in at FT

Unless the PCM is programed to allow it no , The trans can only do what the PCM tells it to and nothing more.

Well it may be his top speed in 3rd but if hes not shifting to fourth because of programing then if he fixes that his top speed would be 30 pecent higher approx 150 mph

Isn't a WOT shift into 4th bad for the transmission?

Yup.. From what I've read 3-4 WOT is a bad thing unless the trans is built for it..
