Just wondering how you like it, and what the correct part # is for it, wanna make sure I buy the correct one for the car! I want to buy one so I can put 4.10's in the rear and have the overdrive to cruise at normal speeds on the highway w/o bein at 5000 rpm! Also does it actually help at all goin 1 - 2 - 2over - 3 at the track like they say it will? Thanks in advance for any info you can provide me with!

There used to be a guy on here who had one, I was considering doing it to mine, but if I ever decide to go with anything overdrive I'll sell the TH400, and get a 4L80E..
