Hi all,
I have a 2001 F350 7.3 PSD auto 3.73 gears 4x4. I really want a tuner, and I like what I see at PHP. I have had one concern all along that has kept me from pulling the trigger- how will this tuner effect the lifespan of my transmission? I have 138K on the truck now, the tranny seems fine. I also checked my tranny manufacture date, and do not have the mechanical diode
. So, is it necessary to get a valve body from somebody like BTS in order to preserve my transmission? I'm not looking for anything crazy here, just better fuel economy, more drivability, towing a horse trailer (about 8-9k) and PERHAPS the occasional trip to the track (like once a year, Diesel Nationals
). How will my tranny hold up to a PHP chip, with and without an aftermarket valve body?
Thanks,
Jack
