Late 1150 crawler(1971-72ish), drives good for a couple minutes, but then the pressure to the TC/and transmission drops and it won't move.

New Hytran, new filter.

Cleaned the screen in tank and the one under your left foot.

Any thoughts?

Let it sit for half an hour and it will work great for a couple minutes again.
 
it sounds to me like maybe your suction hoes may be clasping also i know you checked the oil the dip stick for transmission is under the seat
 
Hello did you solve the problem on the transmission? because i have the same problem my 1150G case dozer stopped moving foward and reverse and i shut down and wait for a couple of minutes and then start the motor and move again. i change the trans fluid, filters, and it happen again. any advice?
 
I have a 1450B dozer and it was working fine, I shut it off for about 10 minutes and when I started it back it would only move in 1st and 3rd, but just enough power to move. when you try to steer with the pedals it just stops. Any ideas?
 

I have just had this same problem occur. I did not see if you had gotten a response as to what the problem was. Did you get yours fixed?

I have a 450 case dozer , it was doing the same as you described . I replaced the trans charge pump and now it runs like a New Tractor . Does the 1150 have a trans charge pump ?
