Hey everybody, I was thinking I have a transmission problem. 1. How can I tell if my trans is slipping. 2. When im driving it shifts what seems to be more times then their are gears could that be the shift solonoids? 3. Cars a 1998 camaro v6 & I did put the transgo hd-2 shift kit in. So any advice would really help. Thanks

Do you think the trans is shifting more times than you have gears because of TCC lockup? It can feel like you have a 5 speed car if it locks in 3rd and into 4th. If it slips usually the tach wil climb and the car will not accelerate or not move if sitting still.

The converter may be locking during gears and unlocking between then apply a tiny amount of presure to brake petal just enough to turn on braske lights and then drive snd see if it feels normal

No a constant very light presure while acccelerating from and stop and through the gears and see if it feels normal then. On foot on brake one on gas .

Oh ok, one more thing what do you mean by normal? What will this test tell me exactly?

Whats hapening is a tuning issue not a trans issue and the shift kit you used since it more or less does away with PWM (slow apply of the converter) making it bump in after each gear change. I have noted the v6 cars do lock the converter in each gear and unlock during the shift.

So what can I do? Where do you go to get a tune for that?

You would just need to fid someone with HP TUNERS or EFI LIVE and there are a few others . I would post in the V6 forums tuning section and see who does tuning on the V6 camaro. Or you could post in the tuning section here also .

My 96 A4 V6 Firebird developed the P1870 code and a trans shop here installed a Sonnax kit that took care of the problem. I don't think my converter locked up in every gear, just in 3rd and 4th. It was a 1996, though, so they might have changed the tune from 98 up.
I think the Sonnax kit eliminated PWM as well, because from then on, it made a fairly distinct "bump" when the TCC would lock up.
Out of curiosity, do you hear a "grinding" noise when in 3rd or OD and and the converter is locked up? Mine also did this pretty badly after the Sonnax kit was put in. I would be curious to know if anyone else with the auto V6 f-bodies has that grinding noise in the transmission as well.

Yeah I have the transgo hd-2 shift kit in there it helped a lot and I never got the 187 code ever. No grinding sounds at all. I did change the trans fluid three times in the last 6month to really clean it out. Wonder if I should check the trans mount and take out the spacer out of the 1-2 accum thing cause it hits hard from 1-2 gear. Might be wearing something out....
