1998 Infiniti I30

Transmission problem
1998 Infiniti I30 6 cyl Front Wheel Drive Automatic 118, 00 miles

Started slipping in 1st gear & reverse last week. I added 1 bottle of Lucas Transmission Fix and it stopped slipping for 2 days. Now it slips in every gear and does not shift into overdrive. Fluid level is full and smells fresh(no burned odor)
Could this be electronic or should I try another bottle of Lucas Trans Fix?

Try a bottle of Jack Daniels cause you need tranny rebuild
