I have to ask for help. Could not find a thread with similar problemas.
I have a 1999 100 4.2TD 347.000km with the four speed auto and I am not sure what is going on. Engine/gearbox or both?
First I thought that the engine lacks power (maybe it does) The car feels slow and I have to use a lot of pedal to get it going. A nightmare to drive with even a 1 tonne trailer. My 125hp Prado 90 series almost feels stronger.
Pedal to the floor to go uphill. It does not feel like a 204hp engine with 4.2 litres. My 175hp diesel Alfa Romeo with a 2.4TD engine cruises up there with the same trailer.
Slowing down and going around a roundabout is best if I put it in 2nd. If I don't do it I have to use a lot of pedal and it gets a hard downshift.
From standstill with the pedal to the floor it is faster than the prado. But still feels like lots of noise and little go...
Drove down a steep gravel hill and put it in 1st for engine braking and the gearbox made an awful sound after about 15 seconds with some vibration.
Did the same in 2nd at then I can barely hear some of the same noise, but no vibration.
Besides this the car feels "normal" Linear engine power. Smooth gearshifts under normal driving.
Gearbox oil is recently replaced at a Toyota dealer.
No stored fault codes.
Maybe diesel pump or Turbo failure? (No Turbo sound)
Or is the gearbox about to go the same way as my front diff recently did? Found info online that a gearbox about to fail could make the car feel lazy.
Cheers
