When its cold my tranny slips a little until it gets warm. The other day i got a service engine soon light. So i went to autozone and they said it was a torque converter slynoid code. He said my sylnoid may be sticking. so on my way home i went to take off from a stop light and it just redlined. I barley made it home and it stalled while turning into the drive way to where it now sits. It sometimes will go into gear after a long lag and sometimes it will just rev up as it would do in neutral. I tried putting it through every gear and still nothing. Please help me out. I dont wanna drop the tranny out until i know for sure what is wrong. Thanks
 


its got something to do with fluid pressure for sure. is the fluid in the transmission real red, or is it brown/burnt? kind of sounds like some thing clogged, filter? cannot say for sure, i doubt it is something simple. let us know about the fluid please.
 
Doesn't sound good man, I lifted this off TEP for you.

Neutrals at stops, Shudders on take off: One of the most common problems I have found after the milege gets over roughly 60K miles. The scenario.... You are driving in traffic for a while OR your car has sat for a while and is a cold startup. You put the car in Drive range and it wont move, or if driving you come up to a stop light and in heavy traffic and the light turns green and SUPRISE!!! You are holding up traffic with a car that wont go anywhere. The most common cause of this problem is a worn out inner surface of the Input clutch piston. I will post pics soon so you can better understand why it IS a real problem. Once the inner sealing area wears it can prevent the inner lip seal for the piston from sealing properly. You may find that revving th engine up will finally get the car to move and it will BANG into gear. This is because the pump in the transmission is working harder and moving more fluid thus allowing the added fluid to overcome the leak which prevented the clutch from either initially applying or staying applied. Another area of concern that causes this is a boost valve in the valve body, not near as common but it can cause this problem on a lessor scale. If a fluid/filter service has not been performed in a very long time then a very dirty or plugged up filter can add to problems as it because a major restriction. IF the filter is found to be very dirty on the inside, which can be verified by cutting open the filter, then there are other problems inside the transmission anyways and an overhaul is the only correct way to fix the problem.
 
The fluid was really red. I just went ahead and got it rebuilt. The motor and trans has 141k on it so it pry needed it
