steamdriven 2 Posted September 4 Report Share Posted September 4 Has anyone changed the oil seal ? I just traced an oil leak to the Boot at the top of the transmission where the vertical gear change selector shaft emerges from the gearbox. looking at the parts diagram I am thinking it Is the seal A132F6143S which may be passing oil. Question - how to remove and replace . Does the selector shaft need to come out and if not then how can the seal be removed over the Selector armature , as it looks like the shaft and armature are a single welded piece ?

steamdriven 2 Posted September 16 Author Report Share Posted September 16 Looks like I am alone on this post folks. Anyhow , for the benefit of the Forum, my update is that I approached two well known specialist lotus garages about the gear shift shaft seals and neither had encountered the job before so were unable to advise. This also perhaps indicates that it is a relatively rare Requirement. A lot of Googling later I finally figured that it is possible to pull the spline with the gearbox in situ ( access obviously a challenge until the stock air filter stuff is removed, but fortunately I have an aftermarket cold air intake fitted which makes this, and a lot of other jobs so much easier). From there it is relatively straightforward to replace the two seals. However, some further research and head scratching has led me to strongly suspect that the leak culprit is the gearbox oil breather, which may not be functioning properly. This can lead to seal leakage under high load and temp. Including the leakage that some have experienced from the strange plastic plug that seals a sensor housing on the Aisin box which Toyota use but Lotus do not utilise on the Evora. So here is a general query - if anyone is reading this stuff - is it possible to remove and replace the breather plug assembly ( A132F6252S part 35 on the parts list.?.)

Seanmitch 0 Posted September 29 Report Share Posted September 29 also having this problem but in the diagram it looks like you would be a brave man to pull that shaft in car. and not have anything slip out of place. with this car it is looking like the shift shaft seal and the white plug are weeping. not sure if we want to pursue this leak without having the trans out of car and seperated Quote Link to post Share on other sites
