![]() 92 240 wagn 230k mi AW70
I purchased wagon for a low price over a year ago, knowing the tranny was failing & have since flushed it 3 times and added Lucas. My point is, lately it has gotten a bit worse during the 2 to 3 shift and it doesn't want to stay in overdrive or jumps back into 3rd on the slightest incline. Any chance the overdrive solenoid could be part of the problem ? * I've been looking for a "known" AW71 but no luck, and found an AW70 from a rear ended car w/ 93k mi. But still hoping for an AW71

![]() Is the kickdown cable binding or out of adjustment? That's what I'd check.

![]() You flushed it 3 times and added Lucas?
Did you also clean/change the oil strainer in the pan? I would also try a different overdrive relay. Checking the kick down cable is a good idea too. Does the transmission slip, or merely have problems shifting and staying in gear? |

![]() I've had overdrive issues before, the only symptom (presuming the solenoid is the only point of failure) is that the transmission will never shift into 4th.

![]() Try a new kickdown cable first. Mine was acting similar. Slipping, usually no OD...kickdown cable fixed it.

![]() Thanks gents,
![]() I don't know much about kickdown cable, but will investigate (Slipping occurs mainly on 2 to 3 shift). * First flush produced a nasty grey/brown color. 2nd flush was much better. 3rd flush was conversion to Dex VI & result is bottom end torque improved |

![]() Yep thanks gents !
![]() I created some slack on kick down cable & things instantly improved ! After a test run I did a bit more, & even better. First try I created apprx 1/4-3/8" slack, then next time another 1/8". 2 to 3 shift slip also improved (or was it rainy weather helped cool trans ?) |

![]() Exact specs for that trans. cable adjustment (as you have learned, it matters) can be found on the UK Volvo 700/900 Maint. Pages. Adjusted mine 5 years ago, never had to touch it. You can also find the direct link near the top of the BB homepage.

Thanks, after a third adjustment (created slack) a grand total of 1/2-5/8" the car has no downshift issues(*also not certain but it seems to have stopped slipping ? Or possibly something else going on) A) I suspect that the downshift cable may not have ever been adjusted properly (?) B) I tried downshift button, & it still works perfect THANK YOU |

![]() Great! My 86 740 still shifts great and doesnt slip a year later after I replaced my kickdown cable. The lube goes away in the sheath and they can bind. I recommend blasting oil down in it if you decide not to replace it.
