I have been having this stalling issue when the engine is at full temp at low speed. Can the trans possibly be the problem? I asked this question a year ago when I got the truck and someone replied about the trans possibly being the problem. TFTS !!

 

Assuming you have an automatic transmission with a lockup torque converter ( E4OD ) then yes. If the torque converter is not unlocking when you come to a stop it can make the engine stall. No different than stopping with a manual transmission without pushing the clutch pedal.

 

So why ONLY when it's warmed up ?? Never stalls when its cold. Any idea ?

 

Low transmission pump pressure can cause this. You can put a 0-350 PSI gauge in the trans test port and see if the pressure is dropping. Possible causes of low pressure are low trans fluid, loose/missing internal filter, leaking internal seals, or a worn pump.

 

So only thing I can do myself is check the filter and replace filter and fresh fluid. Correct ?

 

You couldn't put a gauge in the test port and see what's going on?

 

I have a 1997 F350 with 7.3 motor and when i put in reverse it will kill the motor, but if i restart it in neutral and put in reverse it works fine , so same problem a torque converter lockup ?

 

Where is the test port and what kind of gauge?

 

Thanks I googled found a link on FTE. What gauge would you use ?

 

A gauge that reads from 0 up to 350 PSI.
