Hi

I've got an issue with my 96 L400 2.8T Auto Transmission, It was working fine , i changed the front crank seal and to remove the radiator i just clamped the oil cooler pipes as i have done many times before. It was left like this for about 2 weeks and when it was put back together the transmission works fine but seems to boil up the fluid when I go around the block. I have checked for blockages in the cooler pipes and cooler and also changed the fluid but no joy. I have been told there may be a solenoid that would reduce oil flow and cause overheating if it wasn't working properly. Any ideas?

Why did you remove the radiator ? Confused

Change the feed and outlet pipes that you clamped, as you may have crushed them.

Flush out radiator as sediment accumulates at the base of the rad were the cooler is sited.

Make sure the oil level is right by dipping the level as shown in the book, if you don't do it as stated the levels will read differently each time.

Easy enough to get them swapped without removing the Rad. Wink

Hi Guys sorry for the delay, unexpected trip.

okay so I have fully checked for any blockages and flushed the ATF three times as it was a bit black

Now if I check the ATF when cold it is okay. If I take round the block to normal operating temperature then check the level it is halfway up the dipstick.

Still drives okay but when pulling away when hot the power jumps in about a second after pressing the accelerator.

I take it you are keeping it in Drive while waiting for the lights to change? (My L300 takes a second or two to engage drive after pushing the lever from N to D, so I give it that second before pressing the throttle pedal.)

To check the gearbox oil when hot you must check it with the engine running at idle in neutral after first cycling the gearbox through all selector positions there should be a hot mark on the dip stick. Under or over filling can lead to frothing which will result in erratic performance.
