Allison TC 200, TC 300, TCA 200, TCA 300, TCRD 200 1971 Parts Catalog

If you are hunting down a turbine or a stator for an old Allison Torqmatic converter, you have already learned that aftermarket part listings are a gamble. One wrong number means a week waiting for a return and a bay tied up. This catalog is the original Detroit Diesel Allison publication from 1971. It covers the Allison TC 200, TC 300, TCA 200, TCA 300, TCRD 200 1971 Parts Catalog – 62 pages of factory-verified part numbers, exploded views, and service kit lists. No reprints, no digital guesswork.

Allison built these converters for medium-duty trucks and industrial equipment. They are rugged, but after fifty years the name plates fade and the assembly numbers get hard to read. This catalog tells you exactly where to find that number (rear left side of the housing, output end) and how to decode it. Without that number, you are ordering blind.

Models Covered: TC 200, TC 300, TCA 200, TCA 300, TCRD 200

The table of contents lists TC 200, 300; TCA 200, 300; TCRD 200, 300; plus TCO and TCOA variants. The catalog groups them by assembly number in numerical sequence on pages 1-1.1 and 3-1.1. If you have a TC 200 with a different suffix, the section titled MODELS COVERED tells you exactly which A/N range applies. Use the cross-reference in the NUMERICAL INDEX at the back to see superseded or replaced parts.

You Must Know the Converter Part Number

That heading is taken straight from page 3 of the catalog. It is not a suggestion. The name plate carries the Assembly Number (Part No.) and Serial No. Page 4 shows a real example: a TCA 325-119 model with part number 6755390. Write that number down before you open the catalog. If the plate is missing or corroded, you can sometimes cross the transmission serial number through a dealer, but that takes time. The manual warns: “do not send them to Allison” – orders go through your dealer.

Service Kits: Page 13, 14, 15

Three pages dedicated to service kits. These are the pre-assembled groups of seals, gaskets, bearings, and friction materials that you will need for a rebuild. Instead of chasing ten individual part numbers, you order the kit number. The catalog lists each kit with its component breakdown in the SERVICE KITS section. If you are ordering a complete overhaul set, page 13 is where you start. The kits are listed by converter model, so verify your A/N first.

How to Use This Catalog: A Real Example

Page 4 walks through finding the part number of a torque converter turbine. You locate the Basic Converter Section in the pictorial index, then match your assembly number to the exploded view figure. Each part has a reference number tied to a part number in the parts list. The CROSS SECTION foldout at the back of the catalog gives you a cutaway view to identify components by shape. This is not abstract – it is the same procedure a dealer parts counter used in 1971.

Every time I dig into one of these older Allisons, I pull this catalog out. The NUMERICAL INDEX saves hours. It shows the history of each part: current numbers, superseded numbers, and footnotes (RB or R) that tell you whether a part replaces or is replaced by another. That information is missing from aftermarket databases.

Why a Factory Parts Catalog Beats a Database

Online parts lookup tools for these converters often list a generic “torque converter gasket set” that fits everything. It does not. The Allison factory catalog breaks the converter into subassemblies: cover, pump, turbine, stator, and reactor. Each has its own part number and kit. If a part number is starred (*) in the catalog, it is not serviced alone – you must order the next higher assembly. An aftermarket listing will not tell you that. This catalog will.

For professional shops and serious DIYers, the difference between a one-day repair and a three-day parts chase is having the correct 62-page reference on the bench. The 1971 publication date means it is the original source for first-generation TC 200/300 converters. Later service manuals may include updates, but the core parts data comes from this catalog.

Frequently Asked Questions

Does this catalog include torque specifications for bolt tightening?

No. This is a parts catalog, not a service manual. Torque values are not listed.

How do I find the correct turbine part number for a TC 200 converter?

Locate the assembly number on the name plate (rear left side of housing, output end). Turn to page 4 and find the Basic Converter Section in the pictorial index. Match your assembly number to the exploded view figure for the TC 200. The turbine is typically reference number 7 or 8 in that figure. Then go to the parts list for that figure and read the part number from the column. Write down the part number and check the numerical index at the back of the catalog to see if it has been superseded. If the part number is starred (*), you must order the entire turbine subassembly. This process eliminates guesswork and ensures you get the exact factory part.

That is the difference between ordering blindly and knowing exactly what you need. This 1971 Allison factory parts catalog puts the original GM engineering data in your hands – 62 pages of part numbers, kits, and cross-sections. Stop chasing aftermarket mismatches. Access the Factory Manual and get the part right the first time.
