Hello,

I just replaced the K1 spring kit on my 300DT and while I was down there I noticed that my transmission had a 126 number in a few different places. Is this normal or does that mean that the trans was switched out with an SD trans?

If anyone can shed some light on this it would be greatly appreciated because I'm not sure how much fluid to refill it with. I think I might have put too much in...

Thanks.
