Frequently Asked Questions

What years of Accord V6 had transmission problems, and which should I avoid?

The 2003–2004 V6 5-speed autos were notorious for 2nd–3rd gear "flare" and slipping issues. Honda actually improved the design during the 2005 model year, and there was an NHTSA recall (04V176000) for insufficient oil flow to 2nd gear. If your early 7th-gen failed, this low-mileage replacement is the perfect solution.

Will a low-mileage JDM/import transmission fix my slipping Accord?

Yes, swapping in a healthy imported unit is a very common and cost-effective remedy. It saves you from dropping $3k–$4k on a total dealer rebuild. Just make sure to pair it with fresh, OEM-spec fluid for the best results.

Does this fit the 4-cylinder Accord?

No, this specific J30A transmission will not fit any 4-cylinder models. It is engineered exclusively for the 3.0L V6 Accord. Please verify your engine type before purchasing. 

What transmission fluid does it take?

You should strictly use Genuine Honda ATF DW-1 fluid, which is the direct replacement for the older Z1 fluid. Using aftermarket or universal fluids can cause immediate shifting issues. Do not compromise on the fluid quality.

How many miles are on it, and how many speeds?

This is a 5-speed automatic transmission. Since it is directly imported from Japan, it only has between 55,000 and 65,000 miles on it. It has barely been broken in compared to most domestic options.

What do I reuse, and what are the install notes?

You need to remove and reuse all the external sensors from your original, broken transmission to ensure the computer reads everything correctly. You also need to replace the torque-converter seal before putting the unit back in the car. It is a straightforward process for any qualified mechanic.

What's the life expectancy, warranty, and shipping?

We offer a 90-day warranty and fast nationwide shipping so you can shop with confidence. To maximize the life expectancy of this transmission, follow the severe-service fluid change schedule.
