Hoooooray Filip,
(1) Please refer my posts within your previous lengthy thread “3rd and 4th gear not engaging + weird smell”.
(2) I had no qualms in respect of my SVX as I had fitted a pressure gauge which constantly displayed the transmission line pressure so tat it was clearly visible in front of the steering wheel.
But please, don't imagine me as a guy, who is redlining a cold car, etc. I am trying to do my best to be gentle. But even gentleman wanna have some fun sometimes!
My sport has been motor racing and on two occasions I came very close to death! As long as you always drive the car correctly rather than specifically gently, you can have lots of fun.
In all of this, fitting a manual transmission in order to have fun, involves an entirely different set of circumstances and therefore it could be worthwhile.
Cheers, Trevor.
