1965 Daimler v8 - have problems moving from stationary. Depression of the accelerator pedal has no affect until a certain point when suddenly the revs shoot up and the car leaps forward. Also when driving there is a lag before the gears shift up.
Is this a possibility of incorrect transmission fluid?
Many thanks

It could be but it may also be low on fluid. Check the level and condition of the fluid before you get into the more expensive stuff.

Thanks for reply. Level, colour and smell seems ok. Wondering if previous owner has put a modern ATF in the box instead of ATF-A fluid.
Would that affect the gearbox operation?

Hello Herbert,

If I understand you correctly, the engine is not responding to initial throttle application? If so it is an engine problem, because you say the revs thenshoot up and the car leaps forward, as it will do if the transmission is working.
You should have a linear(ish) engine speed increase to throttle travel.

Do you get an even rise in revs with the car in Park or Neutral?

Thanks for your replies.
Engine revs through the range nice and even when in N or P.
Also moves smoothly from rest in Reverse, condition only occurs in forward gears.
Haven’t tried in Lock yet.
I’ve only had the car a few days and have already fractured the flexible pipe on the stainless exhaust system due to the oval silencer boxes being mounted upside down which reduced the ground clearance to about 3” - so can’t really play around at the moment, for fear of annoying the neighbours as it sounds like a tractor.

Certainly sounds like a problem within the gearbox. Perhaps a Jaguar independent or gearbox specialist nearby may be able to shed further light.

Thanks for reply. This was my initial presumption that the last owner used a modern formula rather than ATF A fluid.
Not sure how you drain the torque converter?
