Question Going Around The Bend!!

My transmission was shot - the third and fourth gear had been cooked and the colour of the oil was that of black treacle.
I dismantled the box and replaced all clutches etc but did not remove the front diff. and torque converter. I also replaced solenoids 1, 2, 3 and A.

1. My first mistake was that I overfilled the gearbox.
2 Early trials with a cold transmission would give good gear changes in 1,2 and 3 with 4 being a bit??.When hot and with too much oil then things went crazy as you would expect!!
3. I removed all the oil and replaced to the correct level. Since then the trials have been somewhat erratic - ie gears 1,2 and 3 changing OK when cold but slipping when hot and 4th difficult to achieve at all.
4. I adjusted the brake band + and -- the effects ranging from noise to serious slip in all gears including reverse ( I think!!)
5. The POWER light does not come on when the car is pushed.
6. The POWER light on startup has given the codes 25 (Engine torque control signal ) and 31 (TPS)- but not always.
7. I have checked the TPS on a digital meter and it would appear to be giving correct values. I have cleaned it.
8. At present when hot it is taking ages to go into drive, is slipping in every gear and there is a "creaking" noise.

My thoughts are - has the servo piston got damaged oil seals?
- is there a problem with the lock-up clutch?
- an oil cooling problem??
- OR WHATEVER?????

The car is a late '93 model with 60,000miles.

Any ideas very gratefully received.

Many thanks
Ron

I think your a brave man to tackle an SVX tranny.

Take a look in my locker for TPS testing. It's not an easy thing to test.

Not brave, John just STUPID!!
Anyway, do you think that my sort of problems ( I mean the car!)could be caused by the TPS??

Thanks
Ron

The TPS tells the ECU and TCU where the throttle position is at. If the TPS is really messed up and I mean erratic to a large degree, then it cannot be helping. The thing is a variable resistor with a wiper arm. It is will wear out some day. If it has very small spots of no resistance it will cause a problems.

However, it should prevent the car from going into gear.
The lock-up clutch for the torque converter will not effect the car going into gear or shifting.

Was there a lot of metal filings and clutch/paper in the box when you took it apart?

How did the splines for the clutchs look? These are sometimes called baskets, sometimes they cut if the clutches spin through them.

I have seen some discussion on filling the torque converter after a rebuild but you did not drain yours?

How do you know the selector cable is adjusted correctly?
