A while back I installed a shift kit. Don't drive my car much so not many miles have been put on it since the install. After the install I've noticed my 3-4 shift won't happen until I hit around 60mph or so and only when I let off on the gas. If I keep on the throttle I've gone as high as 70 and no shift. When it does eventually shift into 4th it is with a swoosh sound and a slight jerk. Both the 2nd and 4th accumulator pistons received new seals at the time of install and it was noted that both these pistons fit very tight in their bores. Could my 4th accumulator piston be sticking? I've fooled with the T.V. cable a little but to no avail. The rest of the shifts are perfect. Trans-go shift kit by the way. My other car has a PTS. Should have went with that one.
Any help would be appreciated.
Thanks!
