2001 Saturn SL1 (1.9L) saga:
Thought I'd give you an update on the ongoing saga of the Saturn 2001 SL1 Transmission:
Thought we had it solved with shining up the sticking valve, but not so. Was good for a short time, then began "bumping" on the down shift, I suppose 4th to 3rd, such as when letting of the gas and coming into town off the highway, when it would downshift at about 60km/hr. Then got another slam shift on acceleration from a stop sign.
Mechanic took the valve body apart again but this time when back together and he took it for a test drive he got a slam-shift, but now there was no 4th gear. Well, at least now he experienced it firsthand himself ;-)
Decided to take it in to Trans-Tech for road test/diagnostic. Road test concluded it looked like the transmission itself not the problem. They took the valve body apart twice and still not solved, though did find some gasket issues. Evidently it's the transmission. So had the local mechanic remove the transmission and shipped it in to Trans-Tech for a rebuild. I understand they found the input feed tube was bent or constricted or some such. Of course now all the clutches are rebuilt too and whatever else they do. Should work perfect, right?
Transmission back in the car, but now 3rd gear only. Trans-Tech wants it back to check it again with their breaker box. Only this time will have to get it hauled into the city because too hard on the transmission to take off without 1st gear. Seems strange it's still giving issues because Trans-Tech would have tested it on their dynamometer.
I don't know what fault codes are showing now. Forgot to ask. Will inquire and report back.
