Th350 slipping in first on take off.

[ellisjay2]

Noticed it was starting to slip from stop and go take offs on the way home from work the other night. I guess and hope its time for a filter and fluid change again, last time i did one was last spring maybe, and thats probably over due...but its been riding and shifting fine until here lately. It seems to do it when I feather the pedal, but when I get up on it it goes on and shifts as normal. This is the stock th350 that came with the 2500, so wear and tear im sure is ready to arise...but hopefully after fluid/filter change that will heal her up some.I dont know dealing with the age, I dont know if I should add maybe a little lucas or trans lube agent to fluid change just yet, but we'll see what happens....any suggestions or advice or tips always appreciated....
