Why Buy a 1999 Honda Transmission from Auto Power Source
Every 1999 Honda transmission we list is a real unit on a real shelf, inspected and recorded before it goes on the site. We do not list a gearbox we cannot put our hands on, and the count at the top of this page is the live count of units in stock today, not a catalogue of what the model year could theoretically carry.
The Odyssey is the trap in this model year. 1999 is the first year of the second-generation van with the 3.5L V6, and the 1998 Odyssey was a narrower four-cylinder vehicle on a completely different transaxle. A seller who advertises a "1998-2004 Odyssey transmission" is describing two unrelated parts. We list the 1999 unit as what it is and nothing wider.
The Civic in 1999 came in several specifications off the same 1.6L SOHC engine, and we hold four of them: the VTEC automatic, the natural-gas GX automatic, and the Base manual in both coupe and sedan listings. Each is geared for its own car. A unit that bolts up is not the same thing as a unit that is right, and your VIN tells us which one you have.
The Prelude Type SH is kept as its own part, not a Base Prelude with a badge. It carries the ATTS torque-steering front unit and does not interchange with the Base car in either direction. The Passport is the other outlier — an Isuzu-built, body-on-frame 4x4 with a longitudinal gearbox that shares nothing with the transverse units in the rest of the 1999 line-up.
Everything ships with the same warranty and the same money-back terms as the rest of our catalogue, and our ASE-certified technicians confirm the match against your VIN before a unit leaves the shelf. Text +1-307-441-5554, call 1-877-313-8995, or email info@autopowersource.com and we answer with the specific unit, not a maybe.

1999 Honda Transmission Buying Guide
5 things to verify before buying a used 1999 Honda transmission:
-
Settle automatic or manual first. Every 1999 Honda unit we hold is listed as AT or MT, and that is the hardest line in the catalogue. The bell housing, the mounts and the shift provision all change. If you are not certain which your car left the factory with, your VIN answers it.
-
On an Odyssey, check the generation, not just the year range. The 1999 van is the first of the 3.5L V6 generation. A 1998 Odyssey transaxle is a different part on a different vehicle, so a listing that spans both years is describing two things at once.
-
Know which Civic you have. VTEC, CNG and Base are different specifications of the same 1.6L SOHC engine, and each gearbox is geared for its own car. The CNG GX unit in particular is fleet-built and does not belong in a petrol Civic.
-
Treat Prelude Type SH as its own part. The Type SH carries the ATTS torque-steering front unit. It is not a Base Prelude gearbox with a different badge, and the two do not interchange in either direction.
-
Confirm the match with your own VIN before you order. Your VIN settles the transmission code, drivetrain and build split in one step. Text it to +1-307-441-5554 and we will confirm in writing exactly which unit fits your vehicle before you pay.
Our ASE-certified technicians verify every one of these points against your VIN before any unit ships.
