Which of their springs did you switch out for the K1 & K2?

Thanks,

I don't have the instructions in front of me but, IIRC (which is highly suspect), I replaced the three spring train in the K1 with the 1 purple spring from the kit. I chose the spring that gave the moderate shift firmness (not the softest and not the firmest). For the K2 I used whatever color was directed by the instructions, again replacing the whole spring train (and the plastic bits that hold them together) with just the one spring (with no plastic bits). I have only driven the car 7 miles so far and it worked fine. I'm still trying to get the fluid level correct though. I will drive it about 90 miles today, for my commute. If I have any problems I will note them here. In my case the accumulator (with the new spring) had to be compressed somewhat to get the cover plate back over it so it could be reattached. This concerned me at first with the K1 as it seemed longer than the old spring train. It fit with a little pressure to compress the spring. I followed these instructions, the pics helped a lot.

In his case though, he is using the MB K1 kit, which apparently is for the softest shift because it keeps the 3 (or 2, depending on your tranny) spring train. In my case I replaced the entire assembly (spring and plastic bits that hold them together) with just the spring from the Superior kit. The K1 access hatch is on the forward end (drivers side) of the VB. The K2 hatch is on the same side but the access hatch is rear facing. Others talked about the screws holding the hatch covers being very tight, I did not find that to be the case with mine. I had a small ratchet that the slotted head screw driver bit fit into and they came out easily. Remember this is an aluminum VB so don't tighten too much. Having a screwdriver that fits the slot properly is a plus.

The instructions are not easy to interpret, if you have any questions, I would ask them here (on the forum) to avoid having to drop the pan numerous times. HTH.
