first impressions of TCS 3800 Well, I finally got around to installing my converter. It's a TCS 3800 with a 2.5 STR. Overall I am happy with it. It's not too loose (feels similar to the ST3500 in a friends car), no lockup issues, and it hits VERY hard from a stop.
The only problem I'm having is that, from a roll, the downshifts seem very lazy. With the stock converter, when I would floor it around 25mph, it would shift into 1st gear hard and push me back into the seat. Now it seems to shift into first very soft. The RPMs come up fast, but the car doesn't seem to pull as hard. I have not installed a shift kit in the trans yet. Any possiblity that this would help? If so, any recommendations on brand of shift kit would be appreciated.
Thanks
Jeff

Re: first impressions of TCS 3800 you need a shift kit, then if it still shifts lousy id call Derek. I know that the shift kit will help a lot. It should solve your problem.

Re: first impressions of TCS 3800 You simply can reprogram your PCM for firmer & faster shifts. I just installed a TCS 4200 2.7 STR and I reprogramed my PCM instead going for a shift kit.
Re: first impressions of TCS 3800 Sounds like your getting some tire spin that you are unaware of. Put a set of DR's or ET streets on and mash the gas and if im right your eyes will roll into the back of your head.
Shift kit will only make the car feel more responsive but will not have any affect on speed or ET's. Torque management maybe causeing some of your problems if the tires don't help. If you can,get the PCM tuned to delete TM and increase the line pressure some to help firm the shifts up.

Re: first impressions of TCS 3800 I do think it is possible that I have some tire spin now. It's a little tough to hear over the exhaust.
I was wondering what type of tuning you all are doing when installing a TC. Is it something that I should consider getting Ls1Edit or Predator for and do it myself, or let a shop do it?

Re: first impressions of TCS 3800 I had my car tuned by a professional who used LS1Edit. Ask around and see if there is anyone in your area that has a good rep for tuning LS1 cars, or you could purchase it and try it yourself, but you would be taking a bigger risk that way if you don't have any idea what you are doing.

Re: first impressions of TCS 3800 Is the tuning we are talking about limited to torque management, line pressure, and shift point changes? Or is there more to it than that?

Alot of people don't take advantage of tuning with a converter but it can maximize the full potential of the converter by doing so.
Torque management will delay the transmission shift,more so on the 01-02 model cars. By deleteing it you can speed up the shift just a tad that will allow the car to charge harder through the gears but some claim it will shorten the life of your transmission,that i can't say i have seen.
Line preassure will firm up the shifts and take back some of the slush that the converter gives.
Shift points need to be raised because of the added shift extentions and most of the bolt on LS1s like to be shifted at 6100-6200rpms,from what i have seen. When mine was a bolt on car i would shift at 6200rpms along with a 6400rpm revlimiter.
With all of this done it is possible to gain a extra .1/1mph by doing so. I picked up .5/.07mph by moving my shift points back when i was all bolt ons.
