Fixed it myself. The car sat 4 months and being a 1985 the plates in the tranny were sticking. NAPA has this stuff called LUCAS Transmission Fix. It will do wonders for your Tranny. Cleans and Lubricates Sticking Valves For Proper Shifting. Polymetric film renews worn bands to stop slipping.. Stops hard shifting too. Great styff saved me $$$$$$$$$ in my Corvette. Try it.

Where is 1994 Sportvan downshift relay location


There's no such thing as a downshift relay.Trans downshift is cable actuated.Go to the end of cable at the carb/throttle body,open the throttle fully by hand and depress the black button in the cable connection block,the cable housing will pop and when your driving will automatically reset to where it needs to be.Your done.

1989 pathfinder transmission 3spd w/ overdrive works great when first started, then downshifting starts way early, started after alternater wentbad


Do you mean upshifting starts way early? Going from 2nd to 3rd in other words?
Ireally don't know your transmission,but the alternator problem might've possibly spiked and hurt your shifting solenoids in the ******. don-ohio (:^)

I have a 96 Grand Am 3.1L SFI OHV 6 cyl. The engine has started to rev way up while driving or in park, which makes it hard to stop and the speedometer will work until the car reaches 25 mph, then it goes...


Hi there!

This sames strange but i would say you might have a transmission problem that makes the car revs up because it look like it keeps downshifting after a high Rpm which makes the engine idles high. Good luck

Is the back up switch connected to the shifting linkage of the automatic transmission on my 1988 ford bronco II


If you have the C5 trans, here is the info:

C5 Transmission
  1. Disconnect the negative battery cable.
  2. Raise and support the vehicle safely.
  3. Remove the downshift linkage rod from the transmission downshift lever.
  4. Apply rust penetrant to the outer lever attaching nut to prevent breaking the inner lever shaft. Remove the transmission downshift outer lever attaching nut and lever.
  5. Remove the two neutral start switch retaining bolts.
  6. Disconnect the multiple wire connector.
  7. Remove the neutral start switch from the transmission.

To install:

  1. Install the neutral start switch on the transmission. Install the two retaining bolts.
  2. Adjust the neutral safety switch following the above procedure.
  3. Install the outer downshift lever and retaining nut, and tighten the nut. Install the downshift linkage rod with the retaining clips.
  4. Connect the wire multiple connector. Check the operation of the switch. The engine should start only with the transmission selector lever in N or P.

If it is the:
C3 And A4ld Transmissions
It's on the transmission....


// // 0) preLoad.src = ctl00_cphLeft_chRepairTreeNav_tvTOC_ImageArray[i]; } ctl00_cphLeft_chRepairTreeNav_tvTOC_Data.lastIndex = 35; ctl00_cphLeft_chRepairTreeNav_tvTOC_Data.populateLog = theForm.elements['ctl00_cphLeft_chRepairTreeNav_tvTOC_PopulateLog']; ctl00_cphLeft_chRepairTreeNav_tvTOC_Data.treeViewID = 'ctl00$cphLeft$chRepairTreeNav$tvTOC'; ctl00_cphLeft_chRepairTreeNav_tvTOC_Data.name = 'ctl00_cphLeft_chRepairTreeNav_tvTOC_Data'; //]]> c17hydro_179.gif

97 Honda Odyssey Auto transmission downshifts


Try checking your timing to solve the ping problem, your timing might be too far advanced. For the downshifting problem, I have this same issue on my odyssey, On the top of your efi manifold you will see 2 wires that control your throttle, One of them extends to the transmission and basically lets it know when you are pressing firmly on your gas pedal, telling it to downshift. I would adjust it so the cable has some more slack in it, therefore requiring a harder press on the pedal before downshift, and hopefully a sooner upshift. You can also slightly adjust idling problems if the van is running high while in park or drive while sitting. As for the gas vapor purge code, I would first try replacing the egr valve, its only a couple bucks and takes no more than 5 minutes.

When the automatic transmission downshifts at


Hi, Honestly i would start with the basics first and change the filter and fluid, if you are not getting a check engine light with any transmission codes a filter change should fix the problem. but remember always use atf +4, do not use any transmission fluid but this.

1988 Chevy Suburban transmission


bad design flaw with the transmission kick down cable make sure you are in OD first but if you are then this cable is adjustable it is next to the throttle cable and tells the trans when to downshift only adjust very little increments as this can easily blow your tanni as you may already know this feeling
