I found a brand new Hayden Transmission cooler on craigslist.org for $35.00 and I got around to installing it today.



First I gently removed the front grille by removing the two little screws on the bottom (not sure if oem) and squeezing the clips and gently pulling up and down to release them (didnt break a single one)


Next I removed the skidplate very straight forward located all three (yep I found out I was missing one) bolts within 2mins ... and then I determined which line was the hot side and cold side of the transmission lines. my passenger side was the hot side as it turns out and drivers side was the cold side (contradictory to what I had read on someone elses install)


Then I removed the OEM transmission lines from the hard pipe by gently scoring the line with a razor knife being sure not to score the hard pipe. Then I drained the Transmission fluid because it was soo old it looked like engine oil


After that I installed the new lines (the one supplied by Hayden and a 2' section of 3/8" transmission line I picked up from Carquest) routing the HOT line up along the engine bay and out through the hole that the AC lines pass through to be mounted in the top of the Hayden cooler. The COLD line was routed through the lower portion of the engine bay next to the bottom of the radiatior and AC condenser to be mouned in the bottom of the transmission cooler. This set up made sense to me since hot air rises.


Then I reinstalled the grille, skidplate and consulted the owners manual for transmission fluid capacity (listed as 2QT) then I refilled the transmission with fluid and cleaned up after my mess.

what is the transmission fluid capacity in the 4runners because the manual states 2qts but a little more than a gallon came out of it?

The manual is wrong. Drain and fills take 4-5 quarts not the 2.1 listed. If you drained a gallon out of your trans and only put 2 quarts back in, it's low.
