is my modulator valve bad on powerglide
I just got to drive my 65 chevelle after a 6 year restoration project. When I bought it in 2000, I drove it a bit and the 2 speed powerglide, stock and original to the car, seemed to shift fine from 1-2.
However, it never turned a wheel for the last 6 years until this week. I drove it and find the following:
- it shifts very quickly out of 1 into 2, say if I turn out of my driveway onto the street I only go about 20 feet before it shifts into 2, seems way too soon.
- secondly, the shift from 1-2 seems harsh, almost a jerk, even if I go real easy on the gas pedal.
- if I accelerate from a standing stop using a bit of gas pedal, it will shift out of 1 at a higher speed, but then I get a real harsh shift, almost a bang into 2.
Could this be a bad modulator valve? this would be about the only thing I can do myself. I did change the oil and filter before taking it for the first cruise and the fluid is up to correct level. Any ideas, thanks.
