I would venture to say that there are far more OEM sensors out there than Dodson ones so of course they're going to fail more. My trans has 138k miles on it before the seal failed causing me to change out the sensors since I was in there. They very next day I got a trans code and now my trans has to come back out to replace a faulty sensor making me wish I would have just left the OEM ones in. Fuck that. I'm not sold on these Dodson sensors. They make good gear and clutch components but whatever entity they are buying and branding these sensors from have very poor QC. As far as I know there is no way to even trace them by production or lot number so it's a crap shoot hoping you don't get a bad one. $150-200 for something they bought in bulk and threw in a Dodson box and won't even admit there's a problem.
