Allison TC 200, TC 300, TCA 200, TCA 300, TCRD 200 1976 Parts Catalog

You are staring at a torque converter that looks like it went through a blender. You need parts. Not guesses from an aftermarket website that thinks an O-ring is a universal size. This is the Allison TC 200, TC 300, TCA 200, TCA 300, TCRD 200 1976 Parts Catalog – 50 pages of factory part numbers, assembly breakdowns, and ordering rules that were written by the same engineers who designed the damned thing. No fluff, no reprints, no third-party interpretations. If you are rebuilding a Torqmatic 200-300 series converter, you need this PDF on your tablet or bench. Period.

Let’s cut through the noise. I have been turning wrenches for 28 years. I have seen guys order the wrong turbine because they used a generic parts list from 1985. Then they wait two weeks for a return. Don’t be that guy. This catalog tells you exactly what you need – but only if you know where to look.

Converter Assembly Numbers: Where to Find Them

The catalog does you zero good if you skip this step. Every Allison Torqmatic converter has a name plate on the rear left side toward the output end of the housing. That plate gives you the assembly number (A/N). You need that number before you open this PDF. The catalog lists all converters by A/N in numerical sequence starting on page 1-1 and page 3-1. Without it, you are just flipping pictures. So do yourself a favor – crawl under the truck, wipe off the grime, and write that number down.

Does This Catalog Cover the TCO and TCORD Models?

Yep. The cover says TC 200, TC 300, TCA 200, TCA 300, TCRD 200. But the inner pages 2-3 also list TCO 200, TCO 300, TCOA 200, TCOA 300, and TCORD 300. If you have a TCO variant, you are covered. The catalog was published 16 August 1976 by Detroit Diesel Allison, Division of General Motors Corporation, Indianapolis, Indiana. That is OEM origin. Not a reprint. Not a scan from some guy’s photocopier.

Service Kits and Numerical Index

Pages 13, 14, and 15 list the service kits. These are pre-assembled groups of parts that wear out together – seals, bearings, gaskets. The numerical index in the rear of the catalog cross-references every part number, current and superseded. If an old part has been replaced, the index shows the new number and marks it with an (RB) or (R) footnote. This is how you avoid ordering something that was discontinued in 1982.

Reading the Cross-Sectional View

There is a foldout cross-sectional view at the back of this catalog. Do not ignore it. That drawing shows how everything fits together – the pump, turbine, stator, and all the little clips that hold the assembly together. When you are breaking down a converter, lay that foldout next to your workbench. It will save you from reassembling the stator backward. I have seen it happen.

Ordering Parts: The Factory Process

Page 3 tells you how to order. Pay attention to the starred (*) part numbers. A star means that part is not serviced alone – you must order the next higher assembly. For example, certain turbines require factory balancing. You cannot just buy the turbine; you buy the turbine-and-shaft subassembly. The catalog indents subassemblies and detail parts beneath the main assembly. If you order the main assembly, you get everything below it. If you order a detail part that is not starred, you get only that part. And for the love of all that is holy, include the model, transmission assembly number, and serial number on every order. Do not send orders to Allison – they will bounce. Send them to your dealer.

This catalog is not a repair manual. It is a parts catalog. But if you are doing a rebuild, you need both.

Bottom line: if you are working on an Allison Torqmatic 200-300 series converter from the mid-70s, this 50-page parts catalog is the only source that matches the factory print. No aftermarket garbage. No wrong part numbers. Access the Factory Manual now and stop gambling with your rebuild.

What models does this catalog cover?

TC 200, TC 300, TCA 200, TCA 300, TCRD 200, plus TCO and TCORD variants.

Do I need the converter assembly number?

You do. The catalog sorts converters by A/N on pages 1-1 and 3-1. Without that number from the nameplate, you will be flipping through 50 pages hoping to match pictures. The nameplate is on the rear left side toward the output end of the housing. Get a flashlight and write it down before you open the PDF. Every part number and illustration is keyed to that assembly number. If you skip this step, you are wasting your time.

Are service kits listed?

Yes, on pages 13, 14, and 15. They cover common wear parts like seals and bearings.

How do I order parts using this catalog?

Find the assembly number, locate the figure and reference number in the catalog, then order the part number from your dealer. Include the model, transmission assembly, and serial numbers. Starred parts must be ordered as part of a subassembly.
