I thought that this would be a good topic to have in the Gen 1 MDX Forum.

Abridged Version from jw02.

I have a 2002 with about 90k. The torque converter appears to hunt in and out of lockup when in D5. I can see the tach and hear it shift about every second or two. It started about a year ago when driving around town at about 40 mph. It has been slowly getting worse, happening up to about 50 mph. I avoid it by driving in D4.

I bought my 02 MDX in 2004 with about 35k. The Trans recall was done prior to my purchase. I change the transmission fluid as scheduled, religiously, due to what I read here.

The constant shifting is fairly subtle. The tach jumps up and down about 200 rpm (say from 1800 to 2000 to 1800, etc), about every second at times. I can hear the engine change tone a little as it changes rpm, but nothing like a rumble strip sound. "


D5 Lockup Hunting

I'm having the same issue and was wondering where jw02 made the voltage measurements from while he was driving (from link above)? Does anyone know?

The voltage readings were taken at the solenoids while the vehicle is running and in gears D4 and D5. Either with the parking brake on (not recommended) or with another person holding the brakes down.

You might want to try the following...

1. Check for debris on the Pressure C solenoid.

2. Replace the Lockup Solenoid Set. PN - 28020-P7W-305
