A few general concerns....

I think I have a little bit of the binding problem... I tried to look out for it when I bought the car, but I didn't really know what I was doing that well (the descriptions I got weren't that accurate oh well)...but... when the wheel is turned pretty far, and I' have to accelerate, like, for example, from a parking lot entrance out onto a street, theres sorta a stutter type feeling/noise. I'm guessing thats 'binding'. What causes this?

Also, between gear RPM flares... I read that the 'flare' in the RPMs is caused bya dirty or bad throttle position sensor... if I recall they're about 150 bucks. How are my chances at cleaning one and putting it back together?

Lastly, when I park on a hill so the SVX is pointed upwards (on my mothers driveway) I get in the car, start it, put on the brakes, take OFF the aprking brake, and then put it in reverse. As I'm backing up, like 2 seconds after I start backing up there's a weird noise. It only happens when I park on a steep hill upwards like that. Any ideas?

Thanks guys!

OK... first, that does sound like what binding is. It is caused when the transfer clutches (READ: center diferential) are locked together. This causes perminant 50/50 torque split. The problem with this is all the wheels are spinning the same speed at the same time. because when you go around a corner, the outer wheels need to spin faster to keep up with the inner wheels, it causes this binding.

The shift flares could be normal. The svx is programmed for very smooth shifts which can be mistaken for slipping. Try unplugging the resistor next to the battery (on the inner fender wall) and see if the 'flares' go away.

I have no idea about the last prob.

The last problem is the ABS doing its self test.

It does that every time you start the car and move it, but it is not so noticeable on flat surfaces.

shift flares: The SVX actually turns off one bank of cylinders during each upshift to allow for smoother shifting, this is what you could be noticing.

No, in the general SVX forum SOLARSVX got his transmission replaced, and his mechanic advised him to get a new TPS sensor.... becuase these 'flares' in the RPMS could damage the transmission. Do you remember that? I think Aredub agreed and they both replaced their TPS sensors.

Is this 'ballast' thing in the transmission easy to get to? I'm pretty competent.

Mike it only does this when moving from park to D or R, if the rpm is over 1200 rpm( I think it's 1200 could be 1500). So that it does not bang into gear.

Mine does the flares as a result of the TPS. Cheap solution: keep RPMs at 2k or greater during 2-3 shift. I usually shift it manually anyway, that way it does less "shifting" which should mean less overall wear on the clutches and less heat and such.

Hmm that's not what I read but I could be wrong.

ok manual shifting

is manual shifting easier on the tranny? My guess is yes but I'm looking for opinions..

thanks

Just a note: I delineate "Hold" as a "normal" shift and "Flare" as an abnormal shift. In other words, during a normal shift, the tranny "holds" at about 3 G's on the tach (at shift point), then the needle drops. In an abnormal shift, the tach "flares" from 3 G's to 3.5 or 4 G's before it shifts (there's no doubt that there's slippage) and the needle drops. So, "flares" would not be normal.

If you know what you're doing, yes. Pretend you're the car, would you want somebody mashing the gas pedal while you're trying to shift? Nuh uh. I usually start out with the gear shifter in 2, since the 1-2 shift is pretty sharp, then I accel to 25 mph or so, and let off of the gas a little bit and put it into 3, and the same for D if I get going ~50 and I know I'm not going to have to slow down for a red light ahead or whatever.
