This sounds like a stupid question but I’ll still shoot. I’m looking at installing engine mount spacers (gs430) to get more oil pan clearance. I don’t want to mess with installing the transmission spacers but would not putting them in cause problems? Could the engine being up an extra 10mm cause any issues with the driveshaft or transmission itself? Or just play it safe and put the transmission spacers in aswell.

 

Not sure I understand the question. Raising your engine will raise the transmission as well although less due to angle/distance and this will stress the transmission mounts.

 

Why? If your engine and trans mounts are original I'd replace those first since they're probably collapsed.

 

Are you planning wanting to lower your car an insane amount or something? The only reason I can think you want more room under the oil pan is if you’re planning on raising the whole suspension cradle or something? You could just raise the engine and not worry about the transmission, unless you’re looking for every MM and the engine is hitting the hood or something, then there is no reason to worry about the trans mount
