Parts & Product FAQs

Finding the right part, what we carry, and how our parts are sold.

Last updated November 2026

How do I find a specific part?

Search by part number, OEM number or transmission code (for example 4L60E, 700R4, 46RE, 6L80 or 10R80). You can also browse by vehicle maker, then transmission, then part category: GM, Ford, Chrysler, Dodge & Jeep, Allison and import transmissions. Every transmission uses the same categories, such as Rebuild Kits, Friction Plates & Modules and Gaskets, Seals & O-Rings.

What if I cannot find the part I need?

Call (844) 298-6404, email sales@globaltransmissionparts.com or use the live chat on our site. Tell us the transmission and the part, and a part number if you have one. We add new parts every week and can often get parts we do not list.

Is the stock shown on the website accurate?

Yes. Product pages show a live inventory count, so the stock you see is ready to ship. Most parts ship from our Circleville, Ohio warehouse; some items, such as valve bodies and torque converters, may ship from another of our warehouses.

What if a part is out of stock?

Fill out the back-in-stock reminder on the product page and we will email you as soon as it is back. If you need it sooner, contact us; we may be able to special-order it.

Can I pre-order a part?

We do not take pre-orders online. Use the back-in-stock reminder, or call us about special-ordering the part.

How do I choose the right rebuild kit?

Start with your transmission model (for example 4L60E or 68RFE) and the vehicle year. Kits are in the Rebuild Kits category for each transmission. Many transmissions also have a "Make Your Own" custom kit, where you choose the friction material, steels, filter and other parts. If you are not sure which transmission or kit you need, call us with the year, make, model and engine.

Are your parts OEM or aftermarket?

Both, depending on the part. We offer OE and quality aftermarket replacements for most components. As transmissions age, new OEM parts are not always available, and in some cases an aftermarket part is the better choice because it corrects a known weakness in the original design.

Which brands do you carry?

Brands include Precision International, Sonnax, TransGo, Alto, Raybestos, BorgWarner, and OEM parts from ACDelco and Motorcraft. Each product page names the brand and the manufacturer's part number.

Do you sell high-performance transmission parts?

Yes, for most applications, including upgraded frictions, shift kits and performance hard parts.

Where can I find product details and specifications?

In the details section of each product page, which lists the part number, transmission fit, year range and OEM numbers where we have them. If you need a specification that is not listed, contact us and we will try to get it for you.

Are the product photos accurate?

Yes. We show photos of the actual product, not stock images.

Do your parts come with installation instructions?

Shift kits and some performance parts include instructions. Rebuild kits do not include rebuild instructions. We sell ATSG technical manuals for most transmissions in each transmission's Technical Repair Manuals category.

What is a friction module, steel module or clutch pack?

A friction module is the complete set of friction plates needed to rebuild a transmission; a steel module is the complete set of steel plates. For most transmissions we sell plates three ways: single plates, by clutch pack, or as a complete module.

What do the friction material colors mean?

Colors differ by manufacturer, so treat this as a general guide and check each listing:

  • Tan or yellow: OE replacement material
  • Green: upgraded high-energy material, suitable for all applications
  • Red: performance street and strip
  • Blue: serious racing only

The manufacturers explain their materials here: Raybestos Powertrain and Alto.

Who makes your steel plates?

Our steel plates are made in the USA by Raybestos Powertrain and Alto.

What warranty do your parts have?

New parts carry the manufacturer's warranty against manufacturing defects. The term depends on the maker (for example 12 months / 12,000 miles on TranStar parts), and our Warranty page lists the term for each brand and explains what is covered, what is not, and how a claim works. If you think a part is defective, contact us with your order number and we will handle the claim with the manufacturer for you. See also our Return Policy.

Do you offer volume discounts?

Yes. Many frequently bought parts, such as frictions, steels, gaskets and seals, are priced lower at 10+, 25+ and 50+ units. The price breaks are shown on the product page and apply automatically in your cart. Professional rebuilders can also apply for commercial shop pricing.

Do you rebuild or install transmissions?

No. We sell parts only.

How often do you add new parts?

Every week. If you do not see what you need, contact us and we will try to get it.
