11 Chevy Transmission Cooler Lines Diagram Gordansundus Pre installation. identify the two 1 2” npt x 3 8” barb fittings. using teflon tape or suitable sealant, install the two 1 2” npt x 3 8” barb fittings onto the transmission cooler. identify the 11 32” x 4’ hose and hose clamps. slide one hose clamp on each end of the supplied hose. using a dab of oil, lubricate each end of the hose. This write up will cover the basics of removing and installing 2 out of 3 transmission cooling lines. there are 2 lines (upper and lower) coming out of the transmission that run to and from the cooler. the third line (aux) is an accessory line that runs from the transmission cooler to the radiator thus completing the connection of all 3 lines.
11 Chevy Transmission Cooler Lines Diagram Gordansundus Because of the cold temperature i had a shop take care of this work. the cooler lines out of the transmission run to a thermostatic valve that's located near the bottom of the radiator. the shop pulled the battery, battery tray, and the transmission support in order to replace the line that connects to the drivers side of the transmission. If no oil flows out, with the engine running, slowly add oil at the top of the transmission until fluid begins to drip from the level check bolt; then replace it and close the filler opening. put the car back on the ground and enjoy your new transmission fluid. frankta2. reply like. Just as the heated coolant flows into the top of the radiator. after flowing through the transmission cooler towards the bottom of the radiator (where it is coolest) it returns to the th 400's top fitting (inlet). other chevy trans may flow differently. frankie. The 4l60e transmission cooler line flow is very easy to follow. as the gif above shows, the bottom line is the hot line which sends warm transmission fluid out to the factory trans cooler within the radiator at the lower port in most cases. fyi, some vehicles have the factory cooler on the bottom of the radiator, but simply follow the lower.

Parts from napa; 827 5469, 5470, 5471, 5472 for the four line pieces (about $93, with aaa discount). i also replaced the two trans fittings, thinking that the o rings might leak if scored or compressed (#730 4952 about $15, for the pair). reply like. First, change the transmission filter. even a filter that is slightly clogged will reduce the flow of fluid, resulting in higher friction, and friction builds heat. next, consider changing the smooth transmission pan to a finned automatic transmission pan. by building fins into the pan, you increase the surface area that cool air passes by and.
