Hello everyone,

 

I am facing an issue with my transmission fluid. After my track day, I had major service on my Evora 400 all fluids changed. However, my car is not changing gears smoothly like before especially between 2nd to 3rd to 4th. I went back to the dealer and they found out that about 700ml is missing from transmission fluid so they topped it up and it became good afterwards. But after couple months of driving, the problem came back again. I do not see any leakage under the car or anywhere near the transmission. 

Any idea how to fix this? or did anyone have this issue before?

I would recommend you to place the car in level, but so that you can take a look on the gearbox from below. Remove the floor and remove the "check oil level plug" on the left side of the gearbox, in the rear end - if I remember it correctly. You might be able to stick a finger in, or take a picture with your cell phone on the oil level. It is a relatively quick operation and probably the best starting point.

If the level is OK and the oil type is correct, in worst case the too low level you had for a while might have caused some damage that has generated debris that in turn have damaged the sync rings over time. I think the drain oil plug is magnetic, so next step would be to drain the oil and check the plug. If everything is fine, you could always refill the same oil again.

I had a similar issue once on an Alfa 147, but that was only when going sideways with the gearstick and that was one of the cables that almost had seized due to corrosion from spilled brake fluid. Later a bearing failed from metal chips caused by gear changing issues with the bad cable.

Thanks for your reply mate,

I will be trying that the sooner I have free time to drive it to nearest lotus dealership and let them have a look at it and do that quick test.
