    It's under warrantee for another six months, plus they should do what it takes to get it right..... I just want to put the old one back in and test to make sure everything else seem right with a known quantity..... The flare definitely isn't right, when it loaded it's basically right a 0 vacuum/boost so it's not near full power..... It won't really make any boost until it's close to full throttle..... It also flashes way higher then it should.....

    Got the old converter put back in, hopefully I can test wed night and see what it does..... I can tell already it drives around better, the other one was sloppy loose on the bottom..... I also have some Hy Gard coming so I can give that a try.....

    Took the car out Wed nite with the old converter..... Felt much better, 60ft picked up a tenth and it went 2 tenths faster in the 1/8th..... It went 6.40@108.39 on just over 16lbs, still leaving off the footbrake at around 3400..... Still shows 29% converter slippage though..... I think I am going to put a little gear back in it, plus the Hy gard fluid I ordered came in..... I'll need to try that too..... I do need to send the new converter back and see if they can get it straightened out.....

    I'll be interested in how the HyGard works. Did you go with standard HiGard or the low viscosity?

    Me too.….

    I cleaned the car up some today, and leaft it with the trans fluid draining so I can try the Hy Gard next..... I have read to use a screen filter not a daycron, so I will have to swap that out too.....

    I am also going to call FTI tomorrow and see what they can do with this converter.....

    Frank,

    This build is off the charts, love the quality and engineering. I have so many ideas for my own project from reading thru your thread. Thanks for documenting everything so well, my hard drive is filling up with all your pictures! I am anxious to see updates in the future.

    Mike

    Long overdue update..... I called FTI, and between talking with them and suggestions from a couple others I had a couple things to try..... One question was if the daycron filter I was using could be a restriction possibly causing pump cavitation, which in turn was causing to converter not to fill properly..... and that causing my major converter slippage issues.....

    I already had the pan off waiting for a screen filter to try, this was where my fist issue came into play..... I did not realize there were 2 sizes of the 727 Torqueflight filters and I ordered the wrong one the fist time, the second time I ordered the smaller one but got more large ones..... Was told it was there mistake and they sent me the correct ones, guess 3 times is a charm..... I put everything back together and checked cooler line pressure both before and after the cooler, I also added a pressure transducer to the cooler line before the cooler..... Pressures looked great, so I did some testing around the shop and there was a definite difference then before..... The converter stall is 400-500 rpm tighter then is was before, at least until I leaned on the fluid a little to hard and cooked it a little..... So I flushed everything and put some HyGuard in it, actually about 75% HyGuard and 25% type F..... The fluid change seems to of tightened the converter a couple hundred more rpm.....

    No the next issue presented itself, the cooler feed line started leaking out of the hose end at the trans with the new found cooler line pressure..... So I replaced the line and fittings, now all seems to be good so far..... I did a little street testing, everything seems good and the logs look real good too..... Cooler line pressure seems to hold at 80ish when the trans is around 150 deg..... Next test will be at the track on Wed nite…..

    Well all that was no help..... Car ran a little faster but better air ca account for that..... Converter slippage is no better..... On top of that I think I broke this converter.....

    So here is what my car looked like when I leaft the shop today.....

    Today I got the new pinion in the rear and put the bearing on the new diff, but I need some longer bolts for attaching the gear to the diff..... I also put the drive studs in the new axles, but I am going to see if I can get another set of rear brake caliper brackets from Strange so I can just leave the other on the old axles..... Otherwise I will have to take the bearing off the old axles.....

    Since I was stuck there, I went ahead and disassembled the trans..... Everything looks good except the tip of the band adjustment pin is bent, maybe a little to much line pressure..... I will have to check that out..... I need to get a gasket/seal kit plus a band adjusting pin and put that back together.....
