new transcooler 03 Savana 1500 195K miles unknow service history
planning to use this van as primary tow vehicle, even though the 04 express 3500 has the 6 litre engine
this RV van weights in at just over (empty holding tanks) 8100LBs she tows good but I believe the lighter 1500 will a better option, plus I can see out the rear windows for backing up.
I can backup looking out the driver window for getting lined up then the mirror for completing the back up but am used to just looking out rear window the 3500 RV van has curtains an also peeking tom prevention one way perforated window film.the 1500 only has factory tinted windows.

note I haven't towed in over 6 years of upsiddown world.
here's the oil trans fuild that dripped out the radiator appears burnt but does have a tad of redness image.

plan to pump out an replenish w/ new nurcon6 an replace filter.

new trans cooler front image the trans return line is on bottom not sure if I have it backwards or if it makes a differnce sense the aux cooler feed line is much lower that the radiators feed line?

rear note bypassing the rad. note the fuel injector type clamps (much stronger than (worm gear hose clamps are for wennies),opposite side of orginal flared tube.

prior to cooler install the fluid appeared clean an red on the dipstick otherwise I would have pumped out before cooler install dam.

auxillary cooler 26,000 lbs 15 1/2 x 10 x 3/4 Transmission Oil Cooler kit. image
