| Transmission external cooler placement options |
Subject: Transmission external cooler placement options by DrEvil on 2008/3/4 3:03:13 Lets see what our trans guys here think. I'm adding a small external trans cooler to my truck. The truck is a 99 GMC sonoma 4.3L ext cab 2wd with the 4l60. I use the truck to tow the vette a couple times a year and believe it or not it does very very well. I also use an alum featherlite trailer with elec brakes. My question is placement in the loop. I can put it in series with the stock cooler in the radiator before the stock cooler or after, or I can bypass the radiator all-together. 1: Bypass the radiator. This would eliminate the heating effect from the stock cooler but in cold weather would it cause other issues like the trans not getting up to temp quickly enough or at all causeing it to not shift into OD. 2: Post radiator, see above. Would it cause the same problems in very cold weather? 3: Pre radiator. Would this even drop it down enough to be effective? I'd think that it would cool the fluid but the fluid would then pass through the stock radiator cooler and thus reheat it. Discuss |
