Tremec TKO 2007 Parts Catalog

If you’ve ever spent a Saturday chasing parts for a TKO build, you know the pain of aftermarket catalogs that list the wrong bearing or skip the snap ring groove depth. This Tremec TKO 2007 Parts Catalog is the paper that came from the engineering floor at TTC – not a reprint from a third-party scanner. I’ve got 28 years on the line, and I can tell you: when the shifter fork tabs break or the input shaft pilot bearing seizes, you need the right factory part number, not a guess. That’s what this 25-page document gives you.

Features and Benefits: What Tremec Built Into the TKO

Page 3 of the catalog lists the engineering highlights that matter when you’re swapping gears at 2 AM. Higher center distance – 83 mm from mainshaft to countershaft – means larger gear teeth and higher torque capacity. Close ratio sets (2.87 and 3.27) for racing, internal 3-rail shift system with cast iron forks. Tapered rollers on input, output, and counter shafts. All gears and shafts made from ASTM 4615 grade steel. Single-piece countershaft. Short-throw billet aluminum shifter. Neutral start and backup light sensors. Eight possible shifter locations, dual speedometer pickups (electronic and mechanical), three input shafts, three overdrive ratios. That’s not marketing fluff – that’s the spec sheet you need to verify before ordering parts.

Specifications & Dimensions: 83 mm Center Distance

The catalog dedicates a full page to dimensions and gear ratios. You get tooth counts, shaft lengths, and bearing part numbers. Need to know the countershaft diameter for a pilot bearing swap? It’s in there. This is the same data Tremec sent to OEM assembly lines. If you’re adapting a TKO to a different bellhousing, you’ll use those dimensions to check clearance.

Parts Breakdown: Top Cover, Shift Components, and More

Section A covers the top cover and shift components – detent springs, shift forks, interlock pins. Section B gives you the input shaft assembly with bearing and seal part numbers. Section C is the mainshaft and gears, Section D the countershaft, Section E reverse gears. The case and extension housing section includes the rear bearing retainer and speedometer drive gear. Each part is listed with a Tremec factory number. Cross-reference those against aftermarket suppliers and you’ll avoid the headache of a misaligned shift rail.

What About Torque Specs?

The Parts Catalog is not a service manual – it’s a parts identification book. Torque values for assembly are in the TKO service manual. But if you need the correct bolt length, thread pitch, or grade for the tailhousing bolts, this catalog lists the fastener part numbers. Pair it with TREMEC T5 Transmission Repair Manual WC & STD or TREMEC T-56 Service Manual if you’re switching between transmission families.

7 Systems and Sub-Assemblies Covered

Sections A through E plus Case & Extension and Part Kits cover every replaceable component. Shift balls, shift location conversion kits, clutch housing options – all in the back pages. The part kits section groups bearings, gaskets, and seals into overhaul sets. If you’re rebuilding a TKO, that’s where you start.

Get the Right Part Number the First Time

Stop ordering the wrong input shaft bearing. This catalog eliminates guesswork. Each part is keyed to a factory illustration. The January 2007 revision date means it’s the latest production-era data before Tremec moved to the TKO-xxx suffix system. If you own a TKO built in the mid-2000s, this is your match.

External technical context: Automotive Industry Overview and Automotive Battery are not directly related to manual transmissions, but the same attention to OEM specs applies across the board.

This catalog is a 25-page PDF, fully bookmarked, scanned from an original Tremec publication. Watermarked for copyright protection, but the text and illustrations are 100% readable. You can zoom into the part number tables and cross-reference with your existing transmission.

Does this catalog include torque specifications for assembly?

No. This is a parts catalog, not a service manual. Torque specs require the factory service manual.

How do I identify which TKO model I have?

Check the tag on the side of the case. The catalog lists parts for TKO 500 and TKO 600 models. Match your input shaft spline count and tailhousing length to the illustrations in Section B and Case & Extension.

Are the shift location conversion kits listed with part numbers?

Yes. Pages 19–20 cover shift balls and shift location conversion kits. The catalog gives you the Tremec part numbers for the offset rail shifter kit, the mid-shift kit, and the forward-shift conversion. Each kit includes a diagram showing which rail and lever to swap. If your car’s transmission tunnel conflicts with the standard shifter location, you can pick the correct conversion kit without cutting the floor pan twice. The part numbers are still active from Tremec and aftermarket distributors.

Can I use this Parts Catalog to order parts directly?

Yes. Every part number in this catalog is a Tremec factory number. Provide it to any Tremec dealer or distributor and they can supply the exact component.

Whether you’re piecing together a TKO for a resto-mod or rebuilding a failed unit, having the factory parts catalog on your workbench saves you the trip to the parts store with the wrong bearing in hand. Access the Factory Manual now.
