Pulled our travel trailer to Asheville N.C. First trip since the trans rebuild, and with the new tru-cool max cooler( lpd 47391). Also i installed a temperature gauge. I also took the ecm and had PCM of nc install their mail order tune for towing.
Quite a difference. The truck is no rocket, but much much better on hills, not as mushy feeling. No spark knock at all. It is tuned for 93 octane, but they assured me that 87 will not hurt it, it will just pull timing. I run 93 towing anyway. In fact it used to spark rattle a bit towing even with 93 on a hot day. I'm happy. It will now pull overdrive on level towing, it did not have the torque to do it before( trans was rebuilt to allow towing in od). About a 4900 lb travel trailer. 3.73 rear end.
The Glow shift gauage is great as my truck is too old to give you trans temps on the dash.
Overall quite pleased.
This was an hour or so into the drive, 147 f !! nice and cool. In fact the hottest trans temp i saw was going up black mountain. I was in 2nd gear pulling about 3500 rpm or so and the temp was 174 f. Hottest i saw the whole trip. This was with a ambient outdoor temp of about 80-84 f.
I highly recommend this cooler!
