Keep your 2020+ Toyota GR Supra 3.0L shifting with the Mishimoto Automatic Transmission cooler. While many enthusiasts might miss the third pedal on the latest Supra's floor, the quick-thinking ZF 8HP mated with the B58 more than makes up for it. However, even with the latest transmission technology, the age-old enemy to sports cars rears its head: heat. The tag team at Toyota and BMW were already ahead of the game by fitting the A90 Supra with an external liquid-to-air transmission cooler, but heavy demand can still be too much. With plenty of room to grow, our engineering team expanded the transmission cooler's core, increasing the volume by 162-percent and the external fin surface area by 412-percent while retaining similar fluid pressures within the system. We also incorporated internal cooling fins to maximize cooling power to maintain proper transmission temperatures, perfect for long days at the track or a spirited drive through the backroads.The Mishimoto Automatic Transmission Cooler for your 2020+ Toyota GR Supra accomplishes all of this with a lightweight, aluminum tube-and-fin core, powder-coated in a sleek silver finish. As with all of our products, this transmission cooler also includes the Mishimoto Lifetime Warranty for a worry-free installation.

Good to know

Questions, answered straight.

If it is not here, call or text the counter. Real people, real answers.

Fitment

  • Will this fit my truck?

    The Fits section at the top of the page lists the manufacturer's applications for this exact part. If your year, make and model is not there, or you are not sure, text us a photo of what you are replacing with your year and engine and we will confirm it before you order.

  • What if I order the wrong part?

    Call or text us before it ships and we will swap it. After delivery you have 30 days to return it in new, uninstalled condition. The return policy has the restocking details.

Shipping

  • When will it ship?

    In-stock parts usually ship within 1 to 2 business days from warehouses across the USA. The stock line under the options tells you the status of the part you are looking at. Large items ship LTL freight and we call to schedule delivery.

  • Why did I only get part of my order?

    We ship from multiple warehouses, so an order with several items can arrive in more than one box. Tracking for each shipment is emailed as it goes out. Full details in the shipping policy.

Returns and warranty

  • What is the return policy?

    30 days from delivery, in new and uninstalled condition, with a restocking fee. Everything is spelled out in the Returns & Refund Policy.

  • How do warranty claims work?

    We are an authorized dealer, so the manufacturer's warranty applies to every part we sell. Call or text us with your order number and we handle the claim with the brand for you.

Paying

  • Can I pay over time?

    Yes. Shop Pay installments are offered at checkout on qualifying orders, and the monthly estimate shows right under the price.

  • What is a core deposit?

    Some remanufactured parts, like injectors and turbos, carry a refundable core deposit. It is shown on the product page when it applies and refunded when your old part comes back to us.
