Which Transmission Cooler?

[Blazer_Boy]

I have a TH700R4 and I want to make sure I don't have any issues with it later on. I've already changed the fluid, filter, and the pan, clean as a whistle. I'd like to add a cooler just in case. I don't to much pulling but I might make some trips out to Colorado Springs and do some ocassional boat pulling. So here's all my specs '82 K5, 350, 700R4, NP208, 31" Michelins, 3.08 diff (upgrading to 3.73).

Here's some eye candy for you to look at

This one is by Perma-Cool, I was looking at it until I saw the B&M one.

Also, what size should I get. I was thinking around the 18,000 GVW size.

I'd go with Perma-Cool. Had a B&M (about 7 1/2" X 12" X 1.5") and it worked OK, but I needed another 5/16" inverted flare tube thread fitting to 11/32" hose barb (like the one supplied with the B&M cooler and, after driving all over Knoxville,TN looking for this type fitting at every car parts, hydraulic and hardware store in town, e-mailed B&M a very explicit letter telling them what I needed, where I'd looked, and asked either where I could get one or who made their's. B&M's answer (through 2 e-mails) was "your local auto parts store should carry these". My third e-mail told them just where they could put their cooler and what I thought of their "customer service". Wrote Perma-Cool asking same and four days later, 2 fittings arrived in the mail (at no cost). I immediately ordered one of their coolers (same physical size) and replaced the B&M! I would use the biggest one you could fit in the space you have available (I could have gone slightly larger but wanted to match the Perma-Cool engine oil cooler installed on the left side in front of the A/C condenser).

I'm not much of a B&M fan either... like you said their service is less then great and I just about threw their crappy shifter outta the garage... eventually replaced it w/ a Hurst. I'm picking up the 18000 Perm-cool on recomendation from my bud who rebuilds trannys at a local tranny shop... in fact he just did mine last week.

I just installed a B&M cooler last weekend. I ordered the largest one from Summit for $49.95. It was a simple install. Took of the grill and mounted it to the front of the AC condensor. I have only 2 complaints. First, there wasn't enough hose with the kit. I had to go to the parts store and buy some more. Secondly, the plastic zip straps that came with the kit were worthless. As soon as I tightened them up, the heads popped off. So I used regular zip ties to hold mine in place.

This is something I will be looking into shortly. Soon as I finish my rear end work. I have an oil cooler on the driver side, and was wondering if I put the tranny cooler in front of the radiator on the passy side, am I going to be starving the radiator of air???

Will work for beer, parts and tools.

I think they are all pretty much the same. Any cooler is better than no cooler. I have a Hayden I got at autoZone and it seems to serve me well. Just get the biggest one you can find. Putting the cooler in front of the radiator will not mess it up, in fact the A/C condenser is the thing your putting it in front of, the rediator is behind it.

The one I have now is a Hayden. I've got the big B&M one in the garage, waiting to be installed if I ever get around to installing the 700R4 that's on the floor. The B&M's certainly look like they could take a lot more abuse than the tube and fin design. I've never dealt with their service dept. Didn't realize they're a bunch of buttheads.

If you buy one that comes with those plastic ties that go through the radiator, throw the ties in the nearest trash can. They don't hold on well enough to deal with the vibrations of off-roading. I've seen them fall off. I've read that they can also wear a hole in the radiator tubes. Mount them with metal brackets, bolted to the radiator support. In front of the radiator works just fine. That's where the coolest air is anyway.
