Colorado Oil Cooler Installation

Greg from Wholesale Automatics demonstrates how to install a transmission oil cooler into a Holden Colorado 7, RG or Trailblazer
Do I need a transmission cooler? Those who tow, carry any sort of load or go offroad should definitely run a dedicated transmission cooler. As the largest 4WD auto transmission specialist in the southern hemisphere we know experientially that heat causes wear, reduces performance and causes costly breakdowns.
At Wholesale Automatics we have model specific DIY transmission oil cooler kits to suit your needs.

Thanks for the instillation guide, was this vehicle your test mule as the transmission temp gauge had me baffled. Could you please tell me the cost of the cooler and what is the average cost to fit.

Awesome great video and content..

[@WholesaleAutomatics]

Glad you enjoyed it

Just wanted to thank you for the video. Was very informative. I'm considering getting one of these. Just a question. Which year was the Colorado that you installed the cooler? Mine is a 09/16, is the transmission the same as the one you installed the cooler in? Cheers Jerome

[@WholesaleAutomatics]

I couldn't tell you sorry Jerome but this cooler fits all 6 Speed RG Colorado, 7 and Tailblazer veriants.

I have a 2016 Chevy Colorado 2.8 diesel automatic transmission was wondering how were your website I live in the US to get a price on that would work on mine

[@WholesaleAutomatics]

We can certainly help you in the US. Just email me [e-mail] and I will send you info on what you need to solve these issues.

Are the hoses realy unprotected under the vehicle or did the video leave out something? Looks like they will rip off easily when offroading.

[@nilz6432]

ok, right at the end of the video Greg tells us about the bash plate.

[@chrisdaquiz7921]

the transmission oil line that you've cut, is that the line going back to the Transmission after the radiator?

[@WholesaleAutomatics]

Yes that's correct Chris.

Just purchased one, will be installing it into a 2018 Z71 with 109km, just replaced filter and fluid, with Nulon Full synth multi vehicle, what temp drop should i expect on the trans after cooler install. Cheers Gaz

[@WholesaleAutomatics]

10-20c under light load and 20-40c under load.

[@Sarge007rocksout]

Did you plumb the new cooler before the radiator? Be better after the Rad to maximise cooling going back to transmission? Stop heat soak in radiator too?

[@WholesaleAutomatics]

Always after the radiator Sarge.

[@Sarge007rocksout]

@@WholesaleAutomatics what about bypassing the radiator cooler all together? Purchased one of your units last week and thinking of full bypass.

[@WholesaleAutomatics]

What model Sarge?

[@Sarge007rocksout]

@@WholesaleAutomatics 2016 rg holden colorado. Exactly like the video, but im thinking bypass all together. I see the inline install is mostly for colder climates and to warm oil from cold. Being in a hot environment i want max cooling so bypass seems better to me
