Transmission Cooler

Hello all,

We are planning on towing our '53 Flying Cloud with a 1995 Chevy G20 V8 cargo van. I know cargo vans are built to haul, not exactly pull so I'm making some modifications. I'm redoing the back end suspension so it operates more like a truck and the brakes.

My question is should I add a transmission cooler to a stock-ish new radiator or should I install a larger Chevy 2500 truck sized radiator?

I am ignorant, looking to see if anyone has done these mods before or has any advice.

Thanks!

I have not added a cooler to your particular van, but adding a larger transmission cooler is never a bad idea, IMHO. I have one of these 45K BTU models on my F250. The only "better" addition would be a fan-cooled unit.

You can add an after market tranny cooler for around $100 and it is worth every penny. You should also invest in an external spin-on filter for another $40, plus a Transgo Tugger shift kit for another $100. All those items installed will double or triple the life of your transmission.

I always added a power steering cooler as well. B&M Racing for trans cooler with cold fluid bypass and Derale for PS cooler.

BILSTEIN shocks, poly antiroll bar bushings, and new hoses, clamps, filters, fluids underhood. Synthetic trans, PS and rear axle fluid. Fresh brake fluid.

Synthetic blend engine oil. Change often first 20k miles.

BRIDGESTONE tires. Duravis models if Load Range E needed.

If Load Range D will work, then see Andy Thomsons recommendation on 16" BRIDGESTONE tires for Dueler line.

Not much to add here but to suggest that what both Pappy & Paula said is right on. Never can go wrong with a transmission cooler if your vehicle doesn't have one, or has a small one. The only caveat is that if you live in cold climates like Buffalo NY 80% of the year, you might want to add a thermostat inline. This way the cooler only kicks on when it's at a certain temp.

Thumbs up

Your trans cooler can be plumbed thru a spin-on filter with temp gauge, worked very well on our 95 Burb.

And for us in the Buffalo area...B & M offers a cooler with a cold fluid by-pass.

That's a great idea. That'll be my next little project.

I do have a magnetic filter in the return line to the transmission. The spin-on remote filter would be a nice addition. What Fram filter is on there?

P & G,

Boy now your asking a lot of these old grey cells...I installed that on our 95 Burb when it was new, can't recall what # it took, common though available every where. The system is no longer available thru Tekonsha.

Thanks, Bob. I'll track it down.

Where are you in the Buffalo area? I have an aunt that just moved from her home of a million years in Cheektowaga to Alden to live with my cousin. Dad's side of the family is from the Sherman area SW of Buffalo.

Transmission Cooler

The thing that sucks about add on coolers is the cheap hoses and hose clamp connections. I almost always use hard lines with flared connections.

A broken hose or a blown fitting..... On hot exhaust components and poof...

Worm-drive clamps should never be used on transmission lines because they don't provide enough clamping force, leading to leaks. Machine screw clamps are available and are the more suitable clamp to use.

Another good addition to go with the cooler is a deep transmission pan with cooling tubes in it, and a filter extension. More available fluid will help a lot. Rolland

I typically cut the steel lines and connect using steel Swagelok fittings to eliminate leaks. The same is true for the flex hose. Pick up quality hose and barbed hose fittings to join rigid and flexible lines. I have never had a problem using machine screw clamps over brass barbed fittings.

Transmission Cooler

I go to NAPA for the high dollar reinforced hose and build them into harnesses following factory routing. Install and remove as a set, no snaking of lines. Use cushioned Adel clamps less than every foot. And I used Magnefine filters for both fluids.

However done it isn't cheap but worth the trouble.
