Helpful Tools: PVC cutter - allows nice clean cuts on rubber hosing

Once again this install is conducted on our '98 Chevy Tahoe- The Transmission cooler purchased for this installation is a B&M Super Cooler. The Super Cooler is a stacked plate design and claims to be 30% more efficient than a tube design cooler. B&M supplies you with enough hose and a variety of screws and ways to mount the cooler. In this case I used their zip tie method of mount which makes it easy to install.

As always please secure the vehicle properly for your safety. This article is only a guideline- all vehicle modifications are made at your own risk.

1. Remove the two lower turn signal light panels, disconnect the bulbs and set aside. Remove the corner light bulbs from their lense and set aside- I tuck all of the bulbs back behind the grille for the time being.
2. Unbolt the bolts from the top edge of the grill and the one bolt underneath the latch mechanism mid way down the grille.
3. DO NOT DO WHAT I DID! I wrestled the 5 bolts I could find out of the lower edge of the grill to find that all I had to do was press three clips- one in the center and 2 towards the outer edge behind each turn signal panel to remove the grill. No harm- no foul but I would have saved myself a good bit of time doing it this way.

1. Remove the 3 bolts from the latch support- 2 at the top, 1 at the bottom.
2. Remove the top 2 bolts from the factory transmission cooler.
3. Remove the 2 bolts holding the AC cooler.
4. Now everything can be carefully leaned forward to gain access to the back of the AC cooler for mounting the Transmission cooler.

1. As per B&M's instructions I kept the factory cooler and added the B&M Stacked Plate cooler in line with it.
2. Remove the outlet side of the factory cooler (be ready to catch some fluid)
3. Place the matching fitting into the outlet side of the factory cooler. (now your ready for a new line)
4. Place where you want to add the new B&M cooler... I did my close to mirror the factory cooler location.
5. Push the zip ties from the back of the AC cooler carefully through to the front.
6. Place the recommended pads to the back of the B&M cooler flange and set in place on the zip ties.
7. After your totally convinced you are sure that is where you want the cooler- double check the clearance then zip tie the cooler in place.

1. Remove the end from the factory metal line. Remove the C-Clip holding the fitting in place and slide the fitting off.
2. Run hose from the outlet on the factory cooler to the inlet on the B&M cooler. (I used a PVC cutter- makes cutting rubber hose a cinch) Don't forget to put the hose clamps on the line before putting the other end on.
3. Run hose from the outlet on the B&M to the hard-line back to the transmission- you may have to work the hose on the hard-line since the flair is so large. Again don't forget the hose clamps.
4. After tightening the hose clamps snug. Replace and retighten the bolts on AC cooler, the Hood latch support and the Factory Transmission cooler.
5. Start the engine- work the transmission through the gears some and check your fluid level (leave it idling of course). Check for leaks and take it for a test drive.
6. There was a noticeable difference in temperature on my transmission gauge. 

1. Put everything back the way you took it apart.... easy as pie- especially if you didn't wrestle those bottom screws off.
