The problem with leaving it "out of the loop" is that there's nothing to warm the transmission fluid and transmission fluid shouldn't be normally operated at temperatures below 150 degrees F. and is optimally run between 175-200 degrees F. Most that bypass usually see around 165 degrees F., give or take, but if you're in an area where it gets really cold, that may not be the case on those extremely cold days. Aftermarket radiators have not had any cross-contamination issues, so far...or, at least, none have been reported...and can be had for $100 or less. IMO, one is better off replacing the radiator than bypassing it.NWPathfinder wrote:Realize this is an old topic but, wanted to chime in and say thanks for the post. I read a bunch of the different threads and will be doing the bypass next week. I'm headed on a road trip and May and don't want any problems!
I had a GMC Acadia that chucked the rad and thankfully didn't infect the transmission but, I've always liked the idea of leaving the Radiator right out of the loop.
Thanks again
