I drained the old ATF and installed a Transgo shift kit with the tranny i the car. I did not drain the torque converter. I want to fill the trans with new fluid. Not being sure what type of fluid is in the converter I would like to drain it and refill with the same fluid as the rest of the trans.

Can I drain torque converter in vehicle and will it refill when I start the engine?

Thanks FBBO
 
I guess it all depends on whether the converter has a drain plug. But yes, it will refill itself.
 
Be sure to let it idle in neutral ... in park I don't think it will fill the TC.
 
Agreed,,,,, PARK dont do jack....
 
If you read the dipstick it says "Check hot idling in neutral".
 
Yes, Sirs; I'll check it in neutral.

By the way, how much fluid leaks out when you have to change the speedo pinion gear? Yes, I need to change my gear.
 
You will need to tap and install a plug to drain the torq converter. yes the transmission pump will refill it. Just will need to keep checking and refilling the transmission afterwards.

Google it and there should be some instructions out there that will show you how to do it.
 
Back in the '80s when I worked for a FORD dealer, we had to buy a torque converter flusher to do warranty transmission work - reason being - without flushing the converter - any foreign objects floating around may still be in there after pulling a transmission and working on it - the OEM said that was the #1 cause for repeat service on transmission work - left over residue and metal in the fluid. I don't know if the MOPAR dealers ever had to do that or not - but it would be a good idea, if rebuilding a transmission, especially one that has a build up of sludge in the pan, to flush out the torque converter to get rid of the left overs so they don't contaminate the new fluid and ruin what otherwise would be a good job. Just thought I'd pass that by everyone - hope it helps.
