help!!!
i have 2001 dodge ram1500 4x4 5.2ltr with a leaking transmission cooler. what is the best easiest fix as i do not want spend $450.00 for the oem cooler. someone must have been there before me. thank you scott

 

Just go to Autozone or similar and get a universal one. IIRC they're about $30-$40.

Cut your lines to the OE one and hook to the new one with trans hose and clamps.

 

ha ha yes we all heard it before but witch one? does size matter? do i install it where it is or in front of the ac cooler and leave the dead on there?

 

what's leaking? the hoses or the cooler itself?
if its the hoses that are crimped onto the hard lines, the best fix is to use a tubing cutter to cut the hard lines, then slip 3/8 auto trans hose over the hard lines and clamp them. use only transmission hose at about $3 per foot from your local parts store.

at the radiator, you can remove the fittings and either replace them with barb'ed fittings, or use the tubing cutter on those too.

if you're not towing something big, you could do w/o the aux cooler and take your time on a replacement, as long as you have the standard cooling in the radiator.

The -1 does not include the cold weather bypass. If you live in a cold climate you'll need that bypass or the transmission might run too cold to engage overdrive.

it comes with 3/8" barbed fittings and a length of hose. I needed an additional length of hose to reach all the way around to the front of the condenser. it did not come with the zip-tie kit, which i got at Advance for about $5-6. tip when installing the zip tie in condenser - place it where you want it and measure it and center it and get it straight and mark the locations for the zip ties with a dab of paint or marker. then using a small screwdriver or nail, gently wiggle a generous hole through the condenser fins. then lift out the condenser and slip the zip ties into the holes from the back side.

 

If you run the tranny fluid thru the aux cooler first then thru the radiator cooler it will maintain proper tranny fluid temp and there will be no issues with overdrive engageing.

the stock radiator cooling system is a far cry from what is best. AUX cooler with a transmission thermostat bypass is what i would do. Its fool proof. There will always be situations where the radiator system will make the transmission to hot or to cold.
