Transmission shifts hard
So I bought this truck used, not knowing when
the u joints were replaced or when the tranny was
flushed, but when I'm accelerating from a stop
and it's coming out of first at rather high rpms like
4K rpms and then when it does shift it will kick
and jerk the truck really fast. It's not really hard ir
anything just kicks back. Is this normal?
No, It's not normal to have to rev up to 4k to shift. Way too high. Unless you are stomping on it. There could be several problems, but if it has high mileage and/or has been abused the transmission could be low on fluid. Do not have it flushed unless the fluid is brown or has a burnt odor. Put the dipstick right under your nose, you will know what I mean. If it is a nice red/pink a flush will do more harm than benefit.
Okay, so what about the kick when it shifts out of first to second, is that Normal? I feel like it's a u joint but I'm not sure. It doesn't really kick when it goes into drive or reverse, only shifting out of first it kicks a little
The truck may have a shift kit in it making the shifts firmer.
Is there a programmer on the truck? If the previous owner had one on and never took it off it may have set the shift firmness to 50-100%.
