Auto gearbox shudder

Oskar - I had a similar problem with my 2008 Navara D40 auto. Shudder when under load around the 80kph mark +/- 3 or 4 kph. Nissan replaced the torque converter under warranty and this fixed the problem. To check if this is the problem or not put the car under a slight uphill load - the shudder will happen with OD engaged but if you turn the OD off it won't happen.....at least that was what was happening with mine.

Hi.
My 03 auto patrol also started shuddering recently going into o/d.
I thought Nissan did an auto service on a major then find out after nearly seven years they don't, converter is now shuddering and a service hasn't quite fixed it.

Could you let me know what the additive is and if it makes any difference, I'm hoping for a cheap fix Atm.

I can add after the service which was done a month ago the auto in only the last week is shuddering less luckily.
