Th 350 gurus.. i need assistance

[mpistolpj]

4 wheeled all day no problems.. than.. after a 4 wheel hole shot from first to second gear under hard power.. I have nothing but park... No real noise to speak of.. shifting mechanism is working properly and it is def. in the tranny.. But no odd noise when in gear.. just no go... I suspect it is a input shaft or pump failure..on the tranny... but i am not a auto tranny specialist and wanted some ideas of what else it could be before i call jackson transmission monday with questions.. This tranny has 8 trips on it after rebuild and never slipped or has gotten hot.. everything was working well until the whole shot.... Any advice is appreciated.

definitely sounds like a hard part failure. have you drained the fluid yet to see if there are any metal pieces in it?

 

[Toddy]

Could be the output shaft. From the sounds of it input or output.

If i am thinking correctly....output should be intact... Becouse i have Park... ... I will pull pan tommorrow and see if i see anything..

mine did something similar, there is a piece that connects the shifter linkage on the side of the trans to a rod that moves in and out on the valve body that selects the gears, mine just came disconnected. when this happened to me all i had was 1st no matter what i did with my shifter.

hope your fix is as easy as mine.

2nd the linkage
but if not i have seen the nose cone on the torqe break0

Ok i have great pressure and volume from the pump(via lines)... I have good movement in the mechanical shifting assembly inside and outside of the tranny... Started removing everything to pull tranny... if anyone esle has input please let me hear it before i tear it out the tommorrow.. thanks PJ

confused.... tranny out... main shaft in tact.. In fact i can turn input shaft and feel it wanting to turn the output shaft a little... No noise.. seems to be fine... torque converter????? Ideas????

Sounds like the Torque Converter to me. When I had my Orange YJ and the Supercharged motor, I killed the TQ converter and it did what yours is doing.

I would say the sprag/center support busted.Has happened to me 4 times during hard 1st to 2nd gear shifts.But I still had low & reverse.

it ended up being that i stripped the internal splines on the torque converter... replaced with a torque converter that had 1/4" more spline engagement. hope this helps someone in the future..Back together and ready for race this weekend.. thanks for the help.......
