going to pull the trigger on a tt3000 on friday got a new 30k cooler and a hughes 7 quart pan in the mail just the other day . cant wait for the install and tune update . how important is the retune with that converter ? can i drive it for a little bit without a retune ?? thanks

yes you can drive it without a retune. i did this for aprox two wks with my 3200. it will however perform and feel better with a retune and prolly get better gas mileage too after u tune the lockup speeds.

You may or may not get a check engine light until it's tuned, it seems to be hit or miss. There are a few shift solenoid, and slippage codes that the flashing of the converter to a higher RPM may trigger. I had a shift solenoid code with my 3k converter until Justin turned that code off. My Circle-D is 258mm as opposed to 278mm of the Yank TT3000 though, so therefore it's looser, and reacts differently than your Yank will, so you may not have this issue.

If the DTC sets, the tranny goes into "limp" mode, and you'll have 3rd gear only. Leaving stops in 3rd gear will kill your transmission quick. Be prepared to need the tune or not drive the truck until tuned, if this happens to you.

my truck is the older lt1 style so the tt3000 is 298mm but if it dose set off codes i have my scan gauge 2 hooked up always so i can reset it on the fly . should only be a week or two untill the tune .

That will work!

ended up with a circle D instead, got a better deal and the money i saved picked up a billet 4th servo. either way i dont think i will be disapointed .

Yep, that's exactly what happened when mine tripped the code Luckily I had my scan tool with me and immediately pulled over and cleared the code so's not to smoke my new FLT Lvl7. I had to baby the truck home and I parked it until I received my updated PCM from Justin.

i am going to send my pcm off to blackbear on monday and get the tune updated for the stall .so i should have it back by the time the converter shows up
