Easy to Understand Information about Honda Transmissions
Common Issues with Honda Transmissions
Harsh shifting, flaring (RPMs go too high) between shifts, lack of engagement (not moving when you shift into gear), and clunking when shifting from forward to reverse are common conditions experienced when there’s a problem with Honda transmissions. It’s important to remember that due to the complexity of today’s computerized transmissions, that just because the transmission appears to be malfunctioning doesn’t mean the actual problem is in the transmission. Your vehicle’s computer gets signals from up to 32 separate sensors throughout the vehicle’s other systems and any one of these could be sending inaccurate or no information.
In order to save yourself from paying for a costly overhaul that may not be needed, please bring it to the professionals for their expert diagnosis.

More About Honda Transmissions
Honda's automatic transmissions are unusual in that they do not use planetary gears like nearly all other makers. Instead, the Hondamatic and its successors use traditional sliding gears in parallel like a manual transmission. Honda was forced to invent their new system due to the vast array of patents on automatic transmission technology held by BorgWarner and others.
Honda initially chose to integrate the transmission and engine block for its first application (in the N360) as in the Mini. The Hondamatic incorporated a lockup function, which Honda called a third ratio, and had manual gear selection. The company's early transmissions also used a patented torque converter which used stator force rather than hydraulic controls for shifting.
The company's naming scheme is also confusing, as it is specific to a single model of vehicle and some identifiers are reused.
