ACDelco10-4003 Limited Slip Axle Lubricant Additive - 4 oz

Q: will this work on my 2007 Z51 Corvette ?

Yes This Additive is for Corvette Limited Slip Diffs from 1953-2009. Note: Refer to your GM Service Manual for vehicle application requirements. Also see: www.mamotorworks.com for Corvette limited slip diff additive part #: 602-970

Q: Can I use in a 2002 trans am 5.7 li automatic trans

If you’re asking about outing it in the axle of your automatic transmission vehicle, yes you can. It is for the limited slip differential which your car came with.

Q: Did they change the chemistry lately, smells different, and mixed into 2 quarts of Valvoline GL5, my posi is crunching off stop in turns.

I have used the same AC Delco limited slip lubricant twice in the past three years on my 1970 Nova with 4.11 gears and posi rear differential. I did not notice any changes in the product however, the old fishy scent from other similar products I have used in the past was not as prominent. Furthermore, I completely drained my differential by removing the cover instead of just draining the old gear oil through the fill/drain plug. I used Lucas Oil (LUC10043 80W-90) heavy duty gear oil when refilling the differential. The Lucas product is supposed to meet or exceed GL5 oil and did not notice any grinding after the service was completed. I am assuming you completely drained your axle if not, mixing different GL gear oils can possibly cause problems. Sorry for the long reply and best of luck with your project!
