I'm sure all this has been covered before buy this is my first CTD so here we go:#1 my tranny seems to shift into OD too soon after hitting 3rd. It shifts into 3rd around 2000-2200 rpm's and almost immediately shifts into OD. the Rpm's drop from 2200 to 1400-1600 when it shifts. Is this normal? Is there anyway to prolong the shift into OD to help keep the power and rpm's up?#2 is it ok to pull small(6000-8000 lbs) loads in OD? It just seems that on the highway at 60+ mph that OD off is just too rapped out. Is it safe to pull in OD at those speeds?
