Does a new torque converter need an easy break-in period?
YES,YES,A new converter does need a brake-in
The way to do it is drive the car or truck at light throttle for about 50 miles then start to increase throttle amount a little at a time, then get up to highway speeds tap the brake (this will allow the converter to lock and unlock)
do this around 50 times to help seat in the new clutch and matting surface
it will take about 150 miles to seat the bearings,roller clutch and the clutch.
DO NOT brake stall or go full throttle with a converter that has a clutch untill this is done!!!
doing this will cause the roller clutch,bearings or the clutch's life to be reduced by a lot!!
Most converter failures happen from brake stalling the converter just after it was installed!
Thank's for asking this!

Before you drive the car, hold the brake and shift through each gear, leaving it in gear, for 20 seconds each gear, to let the fluid circulate. I drove mine gently, until I was sure it locked up, and stalled properly under light throttle. After that, when everything was warmed up, I nailed it.
i drove a few miles untill it was warmed up to make sure everything was shifting and working right. Then wel... after that it was tire smoke. Been working great since 99 knock on wood
Dunno if vig's are made any different or not or maybe i got a good one
50 miles doesnt seem like to far anyway.. just getv to driving and then nail it after 50miles

i would say there is a break in period of say 10-20 miles or so. I say this caues you will want to drive the car and check for any problems like leaking trans lines/leaking pan gasket(some shops change the filter and fluid during a converter install). You will want to make sure all gears work,make sure the converter is locking up/unlocking and you get no codes at all. When this is all done then its fun time. This is just a precaution and is more of a check that everything was installed correctly and there are no computer problems with it. Nothing like blasting down the highway only to find the installers never tightened the trans lines all the way...

Thanks, Mike. I have a heads/cam/longtubes, etc., C5. I have ordered a Yank SS3200 for it and plan on keeping my 3.15 gears. Also, at the same time, I'm going to be installing a Shaner ported throttle body. I know the SS3200 is supposed to be pretty tight, which is why I ordered that particular model as I want maximum drivability, but figured the Shaner would also increase the perception of tightness by increased throttle response.
When I get both installed, I will take the car back for a week, or so, in order to follow your instructions on converter break-in, after which I will let my tuner have his way with it to clean everything up. I will be gettting another dyno run with it, also, and do not want to do that with the fresh converter.
Thanks for the advice, I really appreciate it!

let's go over your instructions. as i do not want to void my warranty because i didn't follow these instructions that were not provided with my converter.
what do you consider light throttle for the first 50 miles?
what is highway speeds? 60? 70? 80?
should i do the unlock/lock 50 times in a row? or say once every 5 miles? 50 times for 100 miles after the first 50 miles.

With Yank Converters as they are all new parts (this is not the case with some other converters in the market as are built out of used parts)
To start with you need to seat the roller clutch in as it takes the over run action ( locking & unlocked and spinning at engine speeds) to polish in the surface of the rollers inner race and outer race or cam in the stator.
also the roller bearings in the converter need to smooth out and polish in,
the clutch surface is still rough as it is new and will need to seat in also
to do this drive normal with no max throttle for about 150 miles (any speed is ok for this)
cycle the clutch this action will work harden the lining material and allow full contact area the same as a brake in on a new set of brake pads and rotors.
when you go WOT it puts a extreme load on the internals and if they are not in shape you can get the roller clutch or sprag to fail and the lock up surface to glaze.
Failure to follow brake-in will shorten the life and effect the performance of the unit.
I will have a complete Brake - in sheet posted on our site soon

Interesting. I have no idea how much of a test drive the shop who installed my trans and converter took after installing it to make sure everything was working properly, but I do remember driving it easy for awhile. After all it was in december when I had it done, so with it being cold out side I didn't really do much but drive around normal.

when will you include it on your boxes when you ship a converter?
now which is it?
