Extra Oil in Trans???

I've been reading about guys putting a full quart of tans oil in their 450X's and having less trouble and mechanical noise with the tranny.

Do yall think this would be ok to do in our 250's??? Would the extra oil add to much pressure and cause the seal between the engine and trans fail prematurely?? or anything like that?

sorry if this has been discussed before. I searched and didn't find what i was looking for.

Sorry bout that I guess i didn search quite hard enough eh?


not a big deal at all

i just put in mercon III per my mech. but i only went to full line not sure about qt thing.

and it only took 1/2 qt till it ran out of hole
