After two fancy Lokar transmission dipsticks, the first with the single 'O' ring as the seal, the second, replaced under warranty is their modified version with two, and I still have a drool of ATF. Of course, since the car is only marking its spot, I probably shouldn't worry about it, but those oily spots in the drive as well as the puddle in the garage are getting to be a PITA. And yes, I have tried different kinds of silicone sealant - and none works as I can't really get that area totally clean and dry while in the car. If the tranny was out and on my work bench, I could probably come up with something, but not as installed.
I went through the Summit catalog and there are probably a dozen different versions for a C4 by ATI, Hughes, Moroso and Miloden as well as Lokar just to name a few manufacturers. Most of these have something that looks similar to a PCV valve cover seal and others have a locking handle as well - which looks like a good addition. Now, my question, have any of you folks ever used any of these other versions besides Lokar? Did they leak? Can one of them be bent if needed to fit my well recessed engine?
