Allison 200 Series, 300 Series, TC-200 1962 Parts Catalog

If you’ve ever ordered a part for an old Allison Torqmatic converter and gotten the wrong stator, thrust washer, or pump assembly because the aftermarket catalog didn’t mention the serial number cut-in, you know the pain. This Allison 200 Series, 300 Series, TC-200 1962 Parts Catalog is the factory-issued document that kills that guesswork. 80 pages, original GM Allison Division print, and every part number comes with the exact application – including those critical “use prior to S/N” and “starting with S/N” notes. No reprints, no aftermarket renumbering. This is what the techs at the Allison plant worked from.

80 Pages of Factory Part Numbers and Supersession Data

The catalog opens with a Foreword dated October 15, 1961, and revised through April 30, 1962 – so this covers the production run when many of these converters were still in warranty. It’s divided into sections like BASIC CONVERTER (page I-1) and PICTORIAL INDEX, TC-200 SERIES BASIC. Group A starts on page I-3 with Figure I, showing the complete TC-200 Series Basic Torqmatic Converter exploded view. You get every reference number from 1 to 30, with part numbers like 451006 (nut, 18 required), 6755221 (gear & cover assembly), and 3702724 (turbine assembly). Each line tells you quantity, availability in service kits (SK 6759026, SK 6759030), and direct cross-references to Service Information Letters – SIL 500, SIL 150, SIL 165 are called out right in the column. That’s the difference between a Saturday job and a Monday tow.

What Serial Number Information Is Included?

The stator assembly (Ref 9) is a perfect example: “Use 6769234 prior to S/N 31823. Starting with S/N 31823 use 3796309 (See SIL 500).” Same for the converter pump thrust washer (Ref 19) – part 3702744 supersedes earlier versions based on the same serial number. If you buy a generic “fits all” stator, you’ll get the wrong freewheel cam engagement or thrust clearance. This catalog lets you match the exact production run of your converter. Also listed: charging oil pump assembly (Ref 23) changes at S/N 31823 from 6755266 to 6773200. Missing that cut-in means a pump that doesn’t deliver proper charge pressure – and a converter that overheats on the first test drive.

3 Reasons to Choose OEM Documentation Over Aftermarket

• Serial number breaks: Aftermarket catalogs often list one part number for the entire production. This catalog shows every change – sometimes multiple versions for the same reference number.
• Service Information Letter references: SIL 500, SIL 150, SIL 165 are printed right alongside the part numbers. You know which factory bulletins apply before you order.
• Genuine Allison Division part numbers: 6750046 snap ring, 3702069 bushing, 3719262 thrust washer – these are the numbers your local dealer or obsolete parts supplier needs to pull the correct stock. Aftermarket renumbering wastes time and often delivers the wrong piece.

Foreword: Factory Direct from Allison Division

The Foreword states: “This catalog contains parts information for all models of the 200-300 Series Allison Torqmatic Converters.” It was published by Allison Division, General Motors Corporation, Indianapolis 6, Indiana. The back page includes a note that the complete line of Allison Torqmatic Drives includes converters, transmissions, and marine units, with literature available from Commercial Sales. That’s the level of authority you want when you’re billing hours on a 1962 tractor or restoring a vintage military vehicle. No third-party summarization – just the original factory document as it left the printing press.

Audience Fit: Who Needs This 1962 Parts Catalog?

DIY mechanics restoring older equipment with Allison TC-200, 200 Series, or 300 Series converters – think graders, loaders, rock trucks, and bus conversions – need this catalog to identify every seal, bushing, and snap ring. Professional shop owners who work on vintage Allison drivetrains should keep one on the bench to avoid the “I thought it was the same part” callbacks. Beginners will find the exploded view and part number list daunting until they realize it’s just a reference – pull the old part, find the number, cross-check the serial number, and order. For more factory documentation, see the related manuals: Allison Torqmatic Converter Series 200-300 Parts Catalog, Allison Torqmatic Converter 200-300 Series Parts Catalog, and 1954 Allison Torqmatic Converter TC-200 TC-300 Parts Catalog. Understanding Allison’s place in the broader Automotive Industry Overview helps appreciate why these converters were used in heavy-duty applications. The internal drive principles also connect to the Internal Combustion Engine’s power delivery requirements.

Does this catalog include torque specifications for assembly?

No. This is a parts catalog, not a service manual. Torque values for converter bolts, pump mounting, and other fasteners are found in the separate Allison service manual for the TC-200/300 series. This catalog only lists the parts, quantities, and serial number applicability.

Can I use this for a 1964 Allison 300 Series converter?

Yes, with caution. The catalog was revised to April 30, 1962, so it covers converters built up to that date. Later production may have additional supersessions not included here. Check the serial number of your converter against the cut-ins listed (e.g., S/N 31823) and order parts accordingly. For converters built after 1962, you need the next revision of this catalog. But for 1961-1962 units, this is the exact document the dealer used.

Every time I see a shop ordering the wrong thrust washer because they used an aftermarket parts list, I think of this catalog. It’s 80 pages, no fluff, no reprints – just the factory part numbers and the serial number ranges they fit. If you work on these old Torqmatic converters, stop burning money on wrong parts. Access the Factory Manual from AutoRepairManuals and keep it in your digital library. Your Saturday job will be done before the tow truck shows up.
