Question about 1994 Volvo 850

1 Answer

I am trying to install a new shift solenoid to eliminate the intermittent trans slipping and solid yellow arrow on the dash ( sometimes flashing/ sometimes off). I do not readily see the switch from below. I was told it is on the driver's side connected to the bell housing. Do you have a picture or better description of location and procedure?

The sensor you have indicated, on the drivers side bell housing, is called an output speed sensor, it is visible from underneath the car. its located over where the right side axle comes out of the transmission, If you would post the codes that you are getting, I have very RARELY seen that sensor cause a problem. Maybe I can offer a better more accurate solution?

94 isuzu rodeo w0nt shift outta 2nd gear why


why double post and not add info????

like engine size ?
4wd?
and trans model.?
best i can tell your trans has no TCM.
so is true hyrdamatic. (no computer brain shifts)
so needs many tests first. to find why it will not upshift to 3rd.
governer? be on top of list.
as is stuck TV cable
or leaking vacuum modulator valve. if it has one.
if you have this trans. on the big V6
then
4L30-E.

see that E on the end, it is TCM shifted.
the trans has a side plate that anyone can read, tells you what is there.
here is the wiki on it.
https://en.wikipedia.org/wiki/GM_4L30-E_transmission


read that?



see the 2 solenoids 425/435?
if yes, that is TCM shifted box, and must be scanned or do the FSM book, TCM flash codes, the book tell you who to do that.

this is a TCM brain auto shifted box, and must be scanned first
if the trans slips, that is a WHOLE OTHER MATTER.

O/d off light flashing


No , the dash being taken apart would not have an thing to do with the transmission , the O/D light flashes when there is a trans problem , code P0781 states there is a problem with 1-2 shift solenoid , Low transmission fluid level , Dirty transmission fluid ,Faulty shifting solenoid valve ,Shifting solenoid valve harness is open or shorted Shifting solenoid valve circuit poor electrical connection

Reverse is rough, with intermittent grabbing, not slippage. I have replaced both s1 and s2 solenoids but dash light arrow still flashes. Prior to replacing the solenoids the transmission was in limp mode...


It sounds as if the seals are bad in your transmission and they are allowing fluid to slip past them. This results in the transmission not completely engaging in gear and being extremely slow to shift into gear.

You can try a few capfuls of break fluid in the tranny. This will swell the seals and allow them to seal better. This is not a permanant fix however, this will only temporarily get your tranny working for an undertermined amount of time. I used this fix on a turbo trans 350 and I got about a year of life out of it.

Beyond that I believe you may be looking at a tranny rebuild or replacement.

1998 ford explorer is having a transmission slip bad. Could it mean that the fluid and shift solenoid needs changing?


Shift solenoid is typically WHEN to shift, not slipping.
Bands and fluid are slipping (and sometimes pump).

Cheap test, remove old, install new fluid... test.
If it works - congrats.
If not, AAMCO or other transmission place for a real test.

Code p0671


P0761 - Shift Solenoid C Performance or Stuck Off

This shift Solenoid is damaged. this explains the erratic shifting you are experiencing. replace this solenoid asap if possible. This shift solenoid is responsible for the engagement of the O/D gear as well.

2000 impala ls trans problem


The problem is a known issue with the 1 to 2 shift at hard throttle. The fix is a repair of the entire 2nd clutch assy. in the transmission. There is a TSB about it released by Chevy. It will need that rebuild for the sudder to go away, or you can try and let off it at shift to stretch more miles out of it.

Transmission slipping


do u have any transmission trouble codes? u should if the OD light is flashing, the light flashes to alert u that a electronic malfunction is occurring in the trans controls, u may just have a bad trans connector or a shift solenoid starting fail due to a shorted field closing coil.
