i'm having issues with a glide. first blamed the new 7"convertor-then new kit -including band-then dual ring accumulator ----pressures within specs--the problem is that it acts like it slips in low gear-went up and down with the launch rpm--3200 #car--327 engine----high gear it seems to hook.what am i missing?----thanks for any help

If it is slipping in low gear it will burn the band up almost immediately. Is the fluid burnt smelling? what makes you suspect that the trans is slipping in low gear? Are you using a trans brake? if the band is slipping the car will try to back up when you get up on the brake.

yep adjust the band check the fluid for smell and make sure the shifter cable is in check meaning its all the way in low gear

Alum or steel drum? Red or Kevlar / Carbon band? What is your adjustment? What was it when you checked it and did you have to change it? What is your line pressure that is in spec? The other guy posting is correct that if it does slip in low gear, its gonna do it a couple times and then stop when it doesn't move anymore. So its usually not something that comes and goes so I think it might be something else you are feeling.

thanks for the input----with my combination i can't get a good 60 ft (1.80) . one time during the burn-out i was told the tires quit turning----with the 7" convertor -456 gears -9"slicks i thought i would at least pick the front end up---i have no burnt fluid-new kevlar band---steel drum---what rpm launch do you think? shift at 8-85----could it be the new convertor?

Is this a foot-braked et-bracket type car? I'm wondering if you got too much converter
for your combo....assuming you went to the 7" after running an 8".

Has the transmission ever worked? Or is this all new? If the converter sprag is broken or fins laid over it will try and stall the engine, pull hard in gear and you have to use lots of brake pressure, and will not Flash at all.

tranny worked good with an other combo--just went though the trans-6 passes on convertor for test- sent back once --too loose of a convertor? i'm frustrated and the end of race here for the winter with no fix

Is this an IHRA class car or a NHRA SS/CS car and what is the low gear ratio? If it is a NHRA class car and your engine is built for high RPMs I believe your problem or at least part of it is your rear gear ratio. My NHRA SS/CS car uses a 6:20 rear gear and a 2:08 1st gear and uses a 7" converter that flashes to around 7600 with the 60's in the low 1.30's.
