Check the ATF fluid color, hope its still bright red! Maybe Trans guy lift out a check ball or spring, converter should lockup at 45 mph. Just a thought.

More info is needed before any guess can be made.
Fluid full? Fluid burnt? Shifter linkage working properly? Filter cracked, broken, or leaking anywhere including the o-ring? Converter bolts verified to be installed, and tight? Forget about the ATSG for the moment. It is very useful on a stock trans. Once major mods are done to the hydraulic's, all bets are off. If you are lucky, you broke the pump, or a the forward apply piston (assuming reverse still works). |

Pete it happend between i drove..there was no noise or bump before this...it was in Drive position...i drove normaly 40 mils/h after some cars infront of me...and then when i tried to accelerate...it was like in neutral... it was not like last time when my 3-4 burnt out...but 1-2 stil worked properly...and the oil was also brown...i hope i dind't burn the clutches.. i have Raybestos blue plate clutches in... Thanx for now.. BR,Seba the trans is in my garage now...so i will disasamble it in a while,,, Quote:

Did you get to take this apart yet? I'm interested to hear the results.
