updated need new advice speedo bounces around at wot and service light on UPDATE NEED HELP:
i replaced teh vss and to no avail did it work right. well i did a lil changing in the tune for the trans and now it shifts good but the service light comes on and teh speedo still jumps all around. i ran it with hp tuners hooked up scaning and the mph were dead on to what i was really going but speedo still jumped around and read wrong. also teh service light comes on when it shifts at WOT(service light not ses) any ideas any one i mean i am stumped also my abs inop light flashe don tehn went off but service light stayed on
i just installed a 383 into my 2000 trans am. and it drives great runs smooth and all. it shifts fine under normal driving, but lets say im cruising at 50 and goto WOT in will downshift as normal but teh hit the rev limiter nemerous amounts of times while its doing this the speedometer bounces from the speed im going over to liek 120 130mph and the when i let off goes back to normal and also i get the traction light to flash on and service light to come on when this happens then goes back off. could this be caused by a bad vss or is it in the tunning. the car was running fine and tranny shifiting great all i did was put the 383 in it ha steh same engine mods as i had before besides its a 383 now. if anyone could help i would apreciate it thanks

i was thinking along the same lines of the vss i was just confused as to if it could be not sending teh correct signal only at WOT but under normal acel it seems to be fine but i will check it out today sometime and see if i can find a problem with it
