Here's where I'm at with this. Changed fluid twice with the filter being changed on the second round. Shifts great(even reverse) except going from 3rd to 4th. If you rev it, it will shift sometimes. If it slips, all will slip until going to neutral then back to drive. Not sure if I should wave the white flag or if there are any other ideas. I'm
assuming TransX will not do anything for it.

Did throw a code for Gear 3 incorrect ratio.

Comments?  Thanks!

seems like it has gotten better? if you think it has, perhaps give it some more time or swap out another drain and fill with the trans-x.

 

you'll still be in for much less than a trans swap.

 

If it isn't getting better - bail out now and call car-part.com or LKQ and shop for a trans, VDCs are not common.

Aside from *maybe* the front speed sensor, I think a correct ratio 4EAT could be used, with the rear section swapped.

 

The H6 4EATs I hear have a beefier part somewhere, but haven't seen pics etc.
