UK 2ZZ/C60 conversion owner with gear selecter issues. Help please :-)

Hi all,

Member from the UK here looking for some advise if possible. I've tried the UK MR2OC but no hits.

To summarise the issue:

Gear changes are all OK when the car is cold albeit a bit notchy but they all engage fine. The more the car warms up the harder they are to engage. Upshifting into 5th is the worst, followed by downshifting into 4th and then downshifting into 2nd. It gets to a point where it wont go into gear without going back into neutral and wiggling side to side a trying again, even then it can still struggle to engage. I have tried double clutching and rev matching to no avail. The hotter the car gets the worse its gets and this is just road use. Once cooled the gear changes are fine again, albeit a bit notchy as mentioned.

By hand in the engine bay with the engine off and clutch out I am able to engage all gears no problem. I have also changed from roller bearing link bushes to solid brass bushes but the problem still exists, car also has the OE shifter with solid base bushes. No obvious signs of wear on the linkages nor cables.

I have read on Lotus forums that the shifter and gate cables can deform and stretch when hot causing the same issues on older cars.

Anyone heard of this issue on the 2ZZ Spyder? Is there a way to adjust (tighten the cables) manually?

Thanks in advance.

Phil

I would suspect the gear oil. How old is it? Check the level. With the car level it should just reach the fill hole. Suggested oil is Redline MT90 or other GL4 spec oil. Do not use GL-5.
