Tranny Cooler

VIII looking for 8s
Ok, so the Mark VIII is up and running again with a 70K mile tranny I picked up from the local salvage yard. Although I attribute my last transmission failure to a junk tranny, I am somewhat concerned about failure due to heat since this one is probably going to see a lot more use. Other than in the winter, my car is a daily driver. I use it to get to and from work and I drive it everywhere else during the year.

I am ready to ditch the two tiny Haynes stacked-plate coolers I have right now and upgrade to something enormous that is going to guarantee me the fluid will stay cool. Can anyone give me any advice on a cooler that will do the job and give me the peace of mind in knowing that my 3800 stall Circle D is not running the trans too hot?

Thanks!!!

You want a Tru-Cool 40K GVWR model - skip the temperature bypass valve.

Thanks driller! :D My decision has been made. You are the second person to recommend that one. :cool: Now to go measure. It sure is tight in the radiator area of these cars. :eek:
 
Did you have to remove the bumper cover to accomplish this, or did you weasel it in there?

It's been a while but I am pretty sure it can be done withe the cover in place.
It goes in from the top. You might have to loosen the top bracket bolts to slide the cooler in between, but other than that it was a perfect fit.
 
It's in!

I got the thermal bypass just in case God forbid my winter car has an issue and I need to drive the Mark VIII to work. This is worst case scenario though and I do not intend on it. Over the next month I will be looking for a winter car that doesn't have mechanical issues but yet is cheap enough seeing as the Mark will be getting further modified this winter. Yet another reason I don't want to deal with the worse case scenario. I'd rather be wrenching on it than wrecking it. :p
