Automatic Transmition overheating Sign In

Hi all

Hoping that there is Auto box Guru that maybe able to help.

Just fitted the Nomad valve body kit from wholesale automatics on the Landcruiser 80 series 12 valve 4.2 diesel. On first test seemed to be working great. Smoother through the gears and even making the truck feel like it has a lot more power.

link deleted ,,,,,,,,,,,,,,, not allowed

Problem is on a long run once the box has got to temp around the 80-90 degree mark and in top gear 4th. If i start coming down hill and ease off the accelerator the temp rockets straight up to 140. I obviously pull over to let cool but if I leave it in Park it still creeps up and I have to turn the truck off.

I have had the ATF replaced for Dexron 3 and the levels look good, transmission cooler looks good ie not clogged.

Any help would be much appreciated.

Cheers

Tom
