2026 POER500 9HAT+Hi4T: Retain Both Names Before Ordering Conventional 9AT Parts
Retain the full Mexican MY26 POER500 Premium 9HAT+Hi4T identity without inferring internal construction or conventional 9AT parts fitment.
A repair order stating only “nine-speed automatic transmission” may send purchasing towards conventional 9AT parts. The factory transmission entry for the Mexican 2026 POER500 Premium states 9HAT＋Hi4T. Keeping the full name helps retain the plug-in hybrid powertrain identity.
Do not shorten the names in the entry
The factory powertrain table separately lists 2.0T PHEV, 9HAT＋Hi4T and a drive-system description including 4L. [T05] This confirms the factory naming, but letters and numbers alone cannot establish internal clutch quantity, motor location or supply relationships between assemblies. [To be verified]
Intake records should separate original powertrain and transmission markings from symptoms. Record actual messages and the operating state when behaviour changes. “Uneven shifting” must not immediately become a diagnosis of a particular mechanical or hybrid-control component.
An equal gear count does not establish shared parts
The 9HAT＋Hi4T equipment name provides no fluid specification, filter-screen construction or seal list. Do not infer filters, oil pans or repair kits from other 9AT models of the same brand, or assume internal parts are separately available from a promotional name. [To be verified] Identify the assembly first, then use the corresponding original repair material to establish the actual purchasing item.
Scope and verification
This article is limited to Mexico; MY26; GWM POER 500; Premium 2.0T PHEV. [Model year and trim basis][T01] Factory equipment information identifies functions and parts; it is not a fault or replacement criterion.
No public data were available in the reviewed material for OE numbers, repair parameters, separate parts availability or compatibility and interchangeability. [To be verified] Compatibility or interchangeability must be checked using the vehicle identification number (VIN) and the local factory parts catalogue in Mexico.
For parts discussed here, use the parts enquiry page.
