It has been shifting very nicely for the last 600 miles.
I have a 2003 Honda Odyssey with 270,000 miles which started to slip when warm shifting 1-2 and 2-3 and had delayed engagement in reverse and drive. This started happening about 30,000 miles after I changed about 1/2 of the trans fluid (4 qts) and the filter with the official Honda stuff. (DW-1 fluid). The fluid I drained out was not horrible but showed use. To remedy this I changed the trans filter again and replaced the four shift solenoids at the recommendation of some experienced advice. The operation was good until the trans got warm. Then it started to slip when shifting and showed the delayed engagement again into reverse and drive. I contacted Lucas chat advice and they recommended the Automatic Transmission Fluid Conditioner. It has been shifting very nicely for the last 600 miles I clocked this past week… including two 180 mile trips. THANK YOU LUCAS!!!
