so i have a fully built 700r4 and i have not had lockup for over a year now...i have a huge cooler tho so it should be ok intell i find out why im not gettin lokcup.....anyways my question is does your tranny make wining noises like a blower/gear drive..ect not when im in P or N but when i put her into D she sure starts to wine and its louder at low rpms the higher you go low lower the noise intell it shifts into 2nt then it will get louder intell higher rpms....anyways just wanted to know if this is normal on a built 700r4 or should i be lookin into it more? i think it sounds good but not sure if it is good!!

 

I have a built 700-r4 - non-locking TQ - it does not make any noise at all. Yours sounds more like the rear-end making noise.

 

My prepped T56 did that..."gear whine" if you will - pretty cool noise, actually. Not sure if that's any help to you, though. Never had a prepped 700.

 

IROZINCO---what does it have in it? cus mine sure has "gear whine".......

 

ok this is what the trans has in it..update 3/4clutch pack...wide 700r4band..forward sprag...low-reverse sprag-wide...HD sun gear shell..large servo kit..throttle valve -boost valve..HD shidt kit....this was all put in when i got it built...then i put a b&m 2200-holeshot lockup in it...i have looked back the paper work from summit and it is a lockup tc. so with that said anyone else have input?

 

i have a new built and it wines did you ever find out what was going on or is this normal? i know this is an old post but please if you found the problem
thanks
