This is where it starts on my page. Could I have missed an earlier part?
Pump bushing: Number 1 in the picture is the OE style babbit bushing. Number 2 is the teflon bushing that trans shops used for the better part of 15 years, and solved a lot of problems with, until one day (circa 2012) they quit making them. I've heard a couple versions of the story but my personal favorite was "they were shipping production of that bushing overseas and the boat carrying all the tooling sank". Numbers 3,4, and 5 are the teflon bushings available today. Notice 2,3, and 4 are a split bushing with a simple butted seam and number 5 is a solid bushing. Number 3 is a sonnax bushing and I think number 4 was from transtar. The bushing saga unfolded after I quit the trans shop and I can't honestly speak for which one of those two would be "better" if any difference at all. I've used whichever one i'm holding at the time AS LONG AS IT'S A SPLIT BUSHING. I've tried pressing the solid bushing (number 5) in on a couple different occasions, and both times they were tight on the converter hub and I didn't use them. I've heard others report the same findings. Number 6 is a "sure seal" bushing by teckpak/fitzall, note it has a rubber o ring in the middle. This is an attempt to keep oil from pushing the front seal out. I've never ran one, as my former boss/mentor told me to run far, far away from them. I'd rather do the proper drainback/seal mods. I wouldn't be surprised if there's a bushing or two I've missed or if there's a cheap knockoff of the split teflons out there somewhere. Anything that's the same as a 700/4l60e and needs replaced in every build is bound to have a wide variety of options.
