In this video we looked at the HO21 converter, which is found in a 1998-2003 Honda Odyssey with a BYBA transmission.

O.E.M. = “Original Equipment Manufacturer”

Video Summary:

There are two common issues you will see with an OEM HO21 converter.  The first is a weak spring bracket, which is not strong enough to withstand repeated lock-up.  What happens is the spring bracket begins to crack and ultimately destroys the torque converter.  The second issue is the outside diameter of the piston body in the OEM design is too close to the lid, which causes it to drag.

To fix the spring bracket, DACCO performs a bridge weld at the stress point, tying the spring bracket to the piston body.  This allows the stress of repeated lock-up to be evenly distributed throughout the entire piston body.  To keep the lid from dragging, we remove .030 from the outside diameter, which keeps the piston body from dragging.

Checkout our installment next week when we talk about the 585Y converter.  Also, leave us a comment and let us know what you think about our videos.
