Trans cooler, too big?

[mplex2000]

Maybe someone can create a "how to plumb cooler lines" thread, this thread probably isn't the best place to argue about it.

As there is a heat transfer between the trans fluid and the coolant, the result is lower trans fluid temp and raised water temp in your cold tank. Thermodynamics don't lie.

Not exactly sure what your asking here? I dont have temp gauges anywhere on my radiators. Normal operating temp on the small block is 180 degrees on the hottest summer day and struggles to get there on 20 below winters. The built 408 ci big block normal operating temp is 195 degrees in 100 degree summer temps and will hit 210 with consecutive hits at the strip. Both motors use manifold senders. I tow the 4000lb big block truck on a 2000lb tandem trailer behind the 350 small block truck with a built 350 turbo. Although I have one on the shelf I've yet to install the trans cooler on the tow rig. I've only had one transmission failure in the tow rig when the low reverse clutch fragged, non-heat related and it let go with nothing on the ball or in the bed. Thanks to Clinebarger I learned to build my own 350 turbo's and duel feed the directs. No slip, no heat although I know i'd get more life out both tranny's with aftermarket coolers installed. I run a 2000 stall in the tow rig and a 3000 10" stall in the big block. Recently, within the past two months the tow rigs 350 turbo began slipping or just not even engaging into drive until that motors warm. Once warm no issues...Yes, I run a 350 turbo behind my big block, no issues after 3 years of pounding out middle 12's in 1300' hits. Radiator heats tranny until radiator cools tranny...Am I wrong? My tow rig is also my daily driver...I think I get what your saying, but I also think thermodynamics works in both direction's? https://www.facebook.com/photo.php?f...9&l=94ea8e38d5
