Just an update on this situation. Dozer is a 550G LT. I think what CJinMI said could be right. Friend had a mechanic I do not know look at dozer and he took some lines loose I guess going to trans pump and he says pump is not pumping. I'm a little skeptical about all this, so I will try and go Thursday and see if I can figure out if pump is working. I'm not sure he got all the oil and water drained, says he can't see a drain plug under their. I think I understand where the microswitch is for the gearshift park position and I will check that. If I determine pump is not working will try to help him get it apart to see what's wrong. I am more familiar working on my Komatsu than a Case. Thanks to everbody that has helped and given me some ideas.
