Default Sluggish shifts

Installed a YANK SS4000 a couple of weeks ago and finally got to take the car for a test ride. It definitely needs a little rpm's to get it moving but I like it. I noticed that the 1st. to 2nd. and 2nd. to 3rd. shift is quite sluggish and the overdrive won't shift until 45-50mph. and sometimes I have to take my foot off of the gas to make that happen. Do I need to have the car re-tuned with this converter? Thanks.

Select your tuner wisely, I have a tune file someone on here emailed me. Done by a popular mail order tuner on this site, painfully obvious why the tune baked his PB trans.

I wouldn't drive it much, if at all until it's tuned, my 3600 was throwing it in limp mode (stuck in 3rd) almost right away. Going from a stock converter to something loose makes it hard to tell it's starting out in third.
I had HP Tuners logging from the first test drive and caught it, tuned it.
Thanks, I really appreciate the info. Definitely don't want to hurt the tranny!.I will have it tuned ASAP.

I have 1 more question. Shouldn't I be showing a code or something if my trans. is not operating properly? Thanks again.

Are you happy with the way it drives?
You can always leave it as is and see what happens.
I guess I'm just used to the tight stock converter and need to drive the car more and get a feel for this upgrade. Anyway, I have to put 150+ miles on it before I can put my foot in it !!!

Hey man, did you get that SS4000 tuned yet? and if so did you use a mail order or a street tune.

I am having the same headaches with the sluggish shifting and lockup issues.

thnx,
Adam
