the saga contnues...
i swapped out my modulator last night and went for a test drive today. i am very sorry to say it made no appreaciable difference. here's what i did:
-replaced modulator
-put modulator pin in a 'midway' setting
-tested vacuum - modulator held vacuum in car, -vacuum looked good, went down from 10 to 0 at full throttle smoothly like it should
-went for a drive. no big difference. doh. i was hoping for some flaring or smoother shifting or something different now that theres some vac present.
i would have expected to at least have some difference, no matter what the setting of the modulator was as long as it was something.
so what do I do now? i have replaced every vacuum component, finding a problem at every stage. is there anything else i can do at this point? can i more directly test whats going on with whatever recieves the vac signal in the trans?
here's some more info for troubleshooting:
-i drained the trans pan last night. fluid was perfectly red. no metal, burning or otherwise bad signs.
-FWIW my transmission looks new.
-im pretty sure i have bad engine mounts and engine shocks. vibrations at idle, engine throbs a lot went shut off. could this affect anything?
- i definitely have bad rear axles, PO drove on them for a while. they creak when car is being driven at low speeds. dont know if this makes a difference. could this make all of the shifts seem poor?
- is there something else that would make the shifts seems poor?
i have a sinking feeling that i am starting to get into painful territory.
please advise....
