Trans bypass questions

[harley hauler]

Hello everyone, new guy here. Ive been doing alot of searching about my new truck, 2001 7.3sd with auto. Ive installed trans temp and boost gauge and so far there are no problems. My concern is high trans temps with the bypass issues, I bought a new bypass for the truck but all is good for now. The truck has 150,000 miles on it and appears to be original trans. How long are these bypass lines good for, or should I replace it before I have a problem. Thanks for any input..2001 7.3sd with superchips 1805

Why do you think you need to change those lines.????

Im not having problems with the trans at all, but reading the other posts in this column I dont want to blow up the trans, from overheating it, when im pulling my toy hauler. On vacation is the last time or place I want to work on my truck. Also, I have read that adding a tuner raises line pressure, possibly causing the bypass to fail. I would like to permanently bypass the line but im not sure how. Thanks again for any input..Harley Hauler

do not take off the bypass line.. its there for a reason.. if for some reason the trans cooler clogs up it bypases that and dumps the oil back into the trans... if you take it off you would cook your trans very quick....

if you want it to last do this...

upgrade the valvebody
install a larger cooler like the 6.0L trans cooler

also get yourself a custom tuned chip that tunes the transmission....

and never heard that a tuner makes a bypass line fail...

10-4 to what raul said.

One would think that if your cooler clogs up, you will toast your trans anyway. Ford claims the bypass is there for extra lube during winter time warm ups.

nope its for what Raul said. Brian at BTS told me that as well

nope, it's what ford engineers say!

definitely dont take the line off! it will be okay for a while, but if that thing ever plugs up your tranny will be running dry....

Ask John Woods why he removes them and how come millions upon millions of automatic transmissions don't have them.
