Im not sure yet how I feel about it but I can get used to it. I know what I was told but I didn't realize how much it would change. It's wered not being able to feel any shifts anymore, I feel like it's a continusly variable transmission now, the rpm's stay at about 3000 until I let off the gas. I havent been able to go more than half throttle yet because of the slippery roads. But I do have a few questions about how it's acting. When I'm moving along and it's locked up if I give it some gas but not enough to unlock it i hear a grinding noise. I'm no expert but I think it's the lockup clutch slipping or the tranny slipping but the rpm's don't go up. Also when coasting to a stop right at 1500 rpm's the car bucks until it goes down past 1400rpm or I give it gas.

 

It does sound like the clutch is slipping, but I'll bet it is a tuning issue. Heads & Cam car often need some tweaking with a smaller diameter converter.

First, I'd reset the PCM and let it relearn with the TCI converter in there. It's probably lighter than stock and that may be contributing to your higher rpm issues.

Also, with a 3000 stall you should be pulling pretty hard if you spin up to 3000 rpm and stay there. Even with my 4200 stall, I generally stay under 3000 rpm in traffic.

 

Nick, it does take a little getting use to when you install your first high stall converter. I think in time you'll probably wish that you would have gone with the SSF3500 converter.
It does sound like your clutch is slipping. Several different things could cause this...PCM programming, physical problems with the trans (ie. a cut or damaged O-ring on the input shaft), or a bad clutch lining (did I just say that? <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
I've only seen one come back with a bad clutch lining. I'd do like Ragtop suggested...reset the PCM and double check your fluid level as well. Give me a call after you check it out.

Thanks for the replys guys. I am slowly getting used to it and I'm starting to like it a lot. I have noticed it likes to pop out of lockup sometimes so I'm going to have to get that programmed as mentioned in another thread (go to the misfire detection temps table - set on temp @140degrees, set off temp @139 degrees). To elaborate on the slipping clutch, it seems to only do it at very little throttle and it kinda sounds like the noise your tires make when you drive on the wake up strips on the side of the highways, and has a little vibration that comes along with it. It seems to have been doing it less and less as time goes on. Can someone elaborate what other programming needs to be done besides the missfire thing. I have my idle set at 950 and shift points at 6100 rpm limit set at 6600.

 

Make sure your cruise Ltrims are negative. This effects the load calculation and line pressure used. Also you might want to increase your lock-up speed (and unlock) by a couple mph to avoid the trouble spots.

You can also play withe your shift points. raising part throttle shift points helps to reduce looseness.
