Identification Locations - Transmissions

When you need a transmission, or transmission overhaul kit, we may ask for model and serial numbers off of the transmission tag. This information is needed due to variations in the types of transmissions used, specific component updates, or serial number related engineering changes that have transpired over years of production.

Even when your request does not involve the engine, there are times that you will be asked for the brand and type of engine. This question is not only for proper engine identification, but sometimes necessary for transmission and torque converter identification as well.

Borg Warner – Transmission tag will be located on top of the converter housing or on a machined block on the side of the transmission. Examples: 1016-000-051 or 1021-000-028 or 1008-052, etc.

Carraro Transmissions – Transmission tag will be located on the filter side of the transmission near the bottom. Note - Some OEM applications have a bar code sticker applied to the bottom of the tag. The customer needs to peel this bar code sticker back to reveal the actual OEM part numbers stamped on the tag. Carraro transmissions are commonly found in Case, New Holland, Volvo and Komatsu backhoe loaders and a wide variety of Telehandlers such as Pettibone and Gehl.

Case Transmissions – Transmission tag location will vary depending on transmission manufacturer.  Possible locations: on top of the converter housing / on the filter side of the transmission near the bottom / on a machined block on the side of the transmission. Case commonly used B/W 1001’s, 1016’s, Carraro TLB1’s in backhoe loaders and Clark Hurth (Dana Spicer) or ZF’s in larger equipment.

Caterpillar CE – Transmission tag locations will vary depending on transmission or transaxle manufacturer and type of equipment. Possible locations: on top of the converter housing / on the side near the bottom of the transmission (on the opposite side of the transfer case if it’s a 4WD unit) / at the rear of the transmission in the lower left hand corner / on the top of the transaxle near the control valve. Note – some transmissions have no tags on them or may have group number rather than an actual transmission assembly number.

Clark Forklift Transmissions – Transmission tag locations will vary depending on transmission. Newer models will be located near the top of the converter housing.

Clark Hurth (Dana Spicer) Transmissions – Transmission tag will be located at the rear of the transmission in the lower left hand corner. Some OEM’s put their tag on the right.

Daewoo/Doosan – Transmission tag locations will vary depending on whether it’s a transmission or transaxle.  Possible locations: on top of the converter housing / on the top of the transaxle near the control valve.

Hyster Transmissions – Transmission part number will be stamped into the top of the transmission case near the control valve or will be on a small metal tag attached to the top edge of the transmission case near the control valve. Numbers will be like T50Mxxxxx, T82Mxxxxx, T90Mxxxxx, designating the transmission model and the unit serial number.

JCB / ITL(International Transmissions Limited) – Transmission tag will be located on the rear of the transmission in lower left hand corner of the main case.

Komatsu – Transmission tag will be located on top of the converter housing.

Mitsubishi – No transmission tag

Nissan – No transmission tag

TCM – Transmission tag will be located on top of the converter housing.

Toyota – Transmission tag will be located on top of the converter housing.

Yale Transmissions - Transmission part number will be stamped into the top of the transmission case near the control valve or it will have a small metal tag attached to the top edge of the transmission case near the control valve. Note -many Yale transmissions have no tags or identification numbers on them. Later models from the mid 90’s forward will have the same "T" number system as the Hyster transmissions.
