Based on all the comments I called Griffin again about a transmission cooler and they don't make one. They recommended B&M units.

I went ahead and purchased the B&M 70264 which does have a cool temperature bypass - $90.

 

now you can run it directly in and out of cooler and skip where it goes in and out of radiator forever eliminating any chance of fluids mixing again and better cooling for transmission fluid, mines never gone over 125 and mostly barely moves off of 100

 

Here are a few pics of my 2003 h2 with Griffen radiator install

 

This would have been great in its own NEW thread. Why tack it on an OLD thread?

 

when i searched this thread came up

 

I am curious on those electric fans.......

 

Best upgrade I have done. Easy to do

 

Got a question. Can I use the OEM external trasmission cooler as a Engine Oil Cooler? Wanna bypassed the radiator internal cooler.
Months back I replaced my OEM Tranny cooler with the larger cooler. Still got the OEM cooler in garage. Any info n tips?

 

Nice upgrade. I like how you asked for advice and then actually listened and acted. Nice clean work. Well done.
