My 99 jimmy with a 4L60E, on a downshift (kickdown) at highway speed or any speed really when downshift by pressing down the accelarator or downshifting by hand the tansmission feels like it's in neutral,...
First off there may be nothing wrong. At highway speed, the trans will shift down to 1st, but you won't feel it. If should feel like neutral. Does it shift normally when your "wide open throttle" from standstill? If it shifts properly in this situation, then your fine, don't worry. How about wide open throttle at say 25mph? how about 35 and 45? anything over that and its gonna feel like neutral. IF your convinced that your passing gear is not working right, it could mean that its out of adjustment, and needs a little more push, more throw, or kinda like adjusting the rod out a little bit further. Adjust your "passing gear linkage" or kickdown as you imply. Second guess would be low on transmisison fluid, filter, and last, the transmissoin control selonoid. Again I suggest its doing just fine, if it shifts down at any speed.
