Do you guys have any reccomendation for a transmission cooler for a 200-r4? Do they cool via pumping transmission oil, engine oil, etc?
200-r4 transmission cooler

B&M makes one, it is basically a little radiator for your transmission; you splice it into the lines (some G-bodies have them incorporated into the radiator.) They are a pretty straightforward install, mount in area behind headlights.

damnit now i have to figure out what i used.
now i know why i didn't ant to remember, it's a ford cooler. 😳

the nice things about it is the "self regulating" feature. you find it on some VERY good, but more expensive, coolers. and a plate style, with mounting kit! for that price is great.

Does that Ford cooler get routed into the transmission oil, or does it get spliced into the coolant system via the radiator? After doing some research it seems for the most part they are all similar. TCI has a pretty decent one that has a switch that activates it when the temp gets above 185 and turns it off at 165 and it has a manual override. I sort of like that one but, the cooler and the switch come out to like $135, a bit pricey..
I'm sure that some super techno-transmission-wizard guy is going to talk next about "optimum transmission oil temperatures," and the like, but I take a different route.
I buy the biggest, RV style external cooler I can get that will fit in front of the A/C condenser and hide behind my grill. I take the one line off of our factory cooler that goes to the radiator. To make sure you get the proper line, take one out and put a bucket underneath the radiator and the transmission line hookup. Have someone else just bump the starter (NOT START THE ENGINE) and see if oil gets pumped out of the line. If it does, this is the line to use for the external cooler. If trans fluid pumps out of the radiator fitting hole that you took the line out of, then you need the other line. The line putting oil inside the cooler SHOULD BE the top one. If it's not, now is the time to fix it.
I cut that line and splice in the rubber hose that comes with the external cooler. That way, without a techinical degree, I can be assured that I am soaking all external heat away from the transmission oil possible and then allowing it to equalize as best it can with the engine coolant in the radiator mounted trans oil cooler. This is also where I put the remote trans oil filter if I decide to use one. I typically only put those on my trailer towing vehicles...
I figured this out, all by myself, without an engineering degree... (oh, boy..)

the ford cooler is spliced into the trans oil (the only way to do it) and has the same directions KRISW posted previously. the "aoto-regulatory" system works well (like the coolant t-stat) since it allows the fluid to heat up enough for proper function, quickly, them maintains it. the coolant only pulls enough heat to keep a STOCK system alive. with my 383 the RPM's are too low and the TC slips too much for the stock trans coolant system to work around town. with the cooler temps are pretty steady.
you should also get a trans temp gauge that splices into the cooler line so you know what's going on. heat is the absolute number one enemy of transmissions. (do i sound like a commercial yet?)

just realized i had the routing backwards. the cooler i used recommended using the fluid coming OUT of the rad and then into the cooler. this way it (hopefully) drops the fluid temp a little first, then the cooler drops it the rest of the way.
the B&M? temp gauge i have has a "green zone" on it for optimum temps. if you somehow operate below it i'd go aux then radiator or just the aux cooler.

I've never had a problem with the oil being too cold in a GM automatic transmission. What supposedly happens?????
When I have done it before, we just spliced some hose onto the hard lines and to the tansmission cooler and then just hung the cooler in front of the radiator with some pieces of coat hanger :lol:
i don't think too low of a temp makes a big difference, but there is an "optimal" temp range. the heat may just help the detergents work better, it will help the oil flow better. it's like with engine oil, you want some heat in there.
