I have a K1 kit on order (and K2 as well) and will install next week. While driving to work this morning the car basically came out of gear between 3 and 4. I put the shifter into 3 and there was no slippage etc then put it back into drive. Came to a stop and the same thing happened again. Once the car was warmed up it shifted much better with a slight flare on the 3 to 4 shift. 1 to 2 shift occurs at 3300 rpm with other shifts at 2000 rpm. Hoefully the K1 and K2 kit will solve it........ If I put the trans under heavy load I don't have the shift problem. Are there other things I shuld look at besides the K1, K2 kit?

I'm in central Iowa with no close trans. shops that deal with Mercedes....
