Tru-Cool 40k trans cooler in 2001 GMC Sierra

After installing a yank ss3600, to keep my
4L60e trans temps cool I decided to install a bigger cooler. I wasn’t sure how to mount it, or what issues I’d run into, so I figured I’d document for anyone else that might be looking to upgrade. Went pretty well, took less than an hour, and
hopefully this video helps someone else!
After the first initial drive, 90 degrees out and the transmission never saw past 140 degrees.

Only video I could find that actually explains enough

[@Teamdeadman666]

Thanks! That’s why I made it, I couldn’t find anything. Lol figured I’d work through it and share.

Bad ass dude I just started on mine 2000 Chevy Silverado short bed lowered 5.3 swap stage 4 cam maddmaxx 4L60 with a 3-3500 stall torque converter can’t wait to drive it and it will be a daily driver also

[@Teamdeadman666]

Hell yea you’ll love it!

[@jesseesquivel6248]

Nice video bro is this truck a daily driver with that 3600 stall converter

[@Teamdeadman666]

Yes it is!

[@jesseesquivel6248]

Do you know bolt measurements of your converter

[@Teamdeadman666]

I don’t off hand no. It’s a yank 3600

[@jamesguralski5156]

Nice! Like the idea of bending that bracket

[@DUKECITYMIKE505]

It’s nice brotha I have a 2000 in red but that grey looks pretty great keep it up 🦾

[@Teamdeadman666]

Thank you! Red is sweet!

[@jesseesquivel6248]

Nice video bro just got my 2000 Chevy Silverado cam how long u been running this cooler

[@BoringFisherman]

My truck has the 4.8 and the trans cooler is in the radiator. I have a k&n intake and filter, and I have side burner exhaust (local exhaust shop did it) I don't have a temp gauge but I notice it gets funky shifting when it's warm after 30-40 miles. I also tow a 3k# boat and I'm considering adding an external cooler, and use the original in series. So essentially double cooled. Do you have any opinion or advice in this situation?

[@jesseesquivel6248]

How long you been driving it

[@Teamdeadman666]

3 years or so now.

[@jesseesquivel6248]

Is that on a 4L60e

[@Teamdeadman666]

Yep!

[@wallywallyblack1]

Just installed.one on my 04 sierra. Love it

[@kennyman338]

It helped 👍 I'm gonna be installing mine this weekend on 07 nnbs tahoe.

[@Teamdeadman666]

Awesome! glad to hear! Was hoping it helped at least one person, lol.

[@vlldavid]

2001 silverado HD I didnt have to cut my lines,I spread them apart and they went in.

[@jesseesquivel6248]

I’m having trouble getting a torque converter did you use 4L60e with v8 flywheel

[@farmalllover8217]

Nice video. Mine has no cooler so I bought one at a junkyard that I’m going to put on. Should I just get a aftermarket one? All mine is getting is headers/exhaust and a bully dog

[@MonteNate123]

How have the rubber hoses held up? If you haven’t already replaced them

[@Teamdeadman666]

They’ve been good for like 10,000+ miles, from whenever date this video was published. No issues yet!

[@MiguelGarcia-yw6qo]

Did you have to bypass the radiator?

[@zmanphx]

My Tahoe uses radiator and the external cooler inline. OEM configuration.

[@MiguelGarcia-yw6qo]

@@zmanphx cool thanks!

[@raymondsalinassanchez9639]

Do you have temp gauge?What were the temps before and after.

[@Teamdeadman666]

So before they were 160-170 ish, sometimes 180-190 in the heat. after I’ve seen like 130-140. Maybe 150 beating on it in the heat. I’m Impressed.

[@mrmotofy]

Always double clamp oil lines, flaring slightly help keep it from sliding off. Or use compression fittings, to a pipe thread and use a threaded hose barb

[@kereckvlogshd2299]

Where did u get a 3600 stall I been having trouble finding one send link

[@vuphung7720]

How was your long trip with the new tru-cool 40k ? Any issues... I’m thinking of doing the same to my GMC

[@Teamdeadman666]

It was perfect. Trans never gets hot. It never saw 150 degrees lol.

[@LuisRamirez-xm7xl]

What did you use to cut the trans lines?

[@97gmc97]

Still holding up good? Fixing to order one myself

[@Teamdeadman666]

Perfect

[@ceasarmiranda526]

link of the cooler?

[@Andres619aa]

do you have a link to where you bought it? i checked ebay and theres multiple of them wanna make sure i get the right one

[@nickunknown1987]

Hows it doing in the winter cause mine came with a little blue bypass for the cooler untill it warmed up and I don't know weather install it or not

[@austindoud273]

Yes install it that'll keep the condensation out

[@casheighty8]

Mounted upside down. The trans doesn’t have enough pressure to fill the cooler past the first inch or two while mounted with the fittings facing down. The goal is to allow the fluid to fill it completely then pressure pushes cooler fluid out

[@Teamdeadman666]

It’s mounted the same as the oem one. It has dropped the temps considerably, so it seems to be working. I would like to make sure it’s being filled properly though.

[@joerivas9847]

@@Teamdeadman666 Ignore the shade tree mechanics. Manufacturer says it can be mounted in ANY position. I wish people would check with the company that built the damn thing instead of, "they said".

[@Teamdeadman666]

@@joerivas9847 I’ve had the thing in the truck for years now. Zero issues. Runs cool. 🤷🏻‍♂️

[@ragingboarsoutdoorinnovati7928]

Would better if u slowed down the mounting of the bracket.

[@Teamdeadman666]

Sorry! I can maybe add some stuff or a bigger break down!

[@JoseTorres-ms2ui]

Surprised your radiator hasn’t cracked yet

[@Teamdeadman666]

is that common? 140k crack-free miles so far lol

[@JoseTorres-ms2ui]

@@Teamdeadman666 yea it’s common mine is 207k and it cracked last week and replaced it with a all aluminum

[@jesseesquivel6248]

Cool

[@robertinman2264]

Did you have to reprogram the ECM when you changed cam?

[@Teamdeadman666]

Yes. The truck was dyno tuned after the cam swap

[@chelseabailey3496]

Video SUCKS AZZ!! Doesn't show which line was routed to radiator nor which transmission port either pressure or return!!

[@Teamdeadman666]

Thank you for your valuable input. The cooler isn’t directional.

[@x-supremacyz2227]

3600 stall wayyyy to big

[@Teamdeadman666]

🤷🏻‍♂️ over a year of ripping sick ass burnouts and hauling ass. Seems to work good for me. Plus it’ll be even better when the truck gets a h/c 5.7 or 6.0
