It upshifts 1 to 2 to 3 fine? Rev is good? Do you have a check engine light on? Sounds like a bad Throttle position sensor.

700r wont shift into overdrive how do u adjust the lets say kick down cable how do i adjust


kick down cables will not operate the over drive
they just select the next lower gear for passing , pulling heavy loads or going up hill.

Travelling at 100 klh @ 2000 revs kicked down in Polo-revs up to 4500 but would not move up gear(s)


run the fault codes to check for TCM or other problem sensor in the transmission. It may be a protection item as it is unwise to kick down at that speed as kickdowns are used to change to lower gears when going up hill or pulling a load and need a lower gear . They are not meant to pass at speed .It is the same effect bas with a manual in overdrive at 100klms and suddenly shifting into 1st gear

Overdrive is kicking in to soon


it can, in fact newer cars do it even more.. .saves fuel....
if fact new cars have fast 1 to 4 gear jump, (no load) MPG feature.
what is it doing and when, and under what loads?????

do you mean downshifting too soon?
OD is top gear. and TCC is torque converter lockup
down shifting happens 3 ways
1: you do it. shifter.
2: low vacuum this is the Load sense, hills cause low vacuum and it down shifts.
3: TV, this is throttle valve , sensed, you stab throttle to pass.
aka; detent, TV. passing gear.
on some cars there is an OD switch to cut out OD, say pulling trailer
pulling any heavy load, may case the OD to hunt, or the TCC to hunt
and is a real pain....

btw the FSM covers all 100 A/T issues, up shifts, down, slips. flare, early ,late. ... its complex device, tend to not own them.

I have a 1999 jeep cherokee that has intermitant transmission problems 1)shifting up it wind out to 2k-3k before shifting 2) at higher speed it feels as if it slips out of overdrive rpm increase but speed...


It will shift out of overdrive upon increasing throttle , pulling hills and so on. Your overdrive probably kicks in around 35 to 45mph and kicks back out as you increase throttle. Electrically controled speed sensor to control the response. Overwise the engine would bog down to a stall. Over drive is just that. It changes the gearing ratio to over drive meaning less then final gear 4 to 1 down to 4 to 3 etc more direct drive ratio to lessen consumtion of fuel with less stress on engine. Have shift speed sensor adjusted. Don't drive in overdrive in city if most driving is under 45mph

Not shifting into passing gear


hi passing gear is actually your transmision drpping down to second gear.if you hit the gas hard.if you hit the gas lightly it will only drop out of overdrive and go into third and not go into passing gear.

1996 3500 TRUCK WON'T SHIFT OUT OF SECOND INTO 3RD OR OVERDRIVE


Their are a few possible causes of this. One their is not enough tranny fluid in it or the kick down cable is not hooked up properly. the kick down cable also runs the vacume to the transmission.

Check theese and give me feed back to further assist you.

Won't shift


This problem could be as simple as the fluid level being low. Or as complicated as a leak in the vacume lines. The problem could also be the kick down cable is not hooked up.

Their should be two cables hooked up to your throttle, IF you do not have cruse control. If your van is equiped with cruse control their will be three cables hooked up to it. Two on one side and one on the other. The one by its self is the cruse control the other two are the kick down cable and the other goes to your petal. If the kick down cable is not hooked up it will not shift right.

Check the transmision fluid level with the van running. If low fill and let it run for 5 min.

If this is not the problem replace all vacume lines that have to do with the transmision.

Please let me know if your problem presists.

Thanks, Charlie

1995 jeep laredo overdrive is not shifting


Your overdrive should kick in at about 45mph, pretty much at or about 2000rpm. To see if it engaged, lightly touch the brake pedal and it will disengage.It should also disengage when you mash the pedal down to go into passing gear, and re-engage when conditions "normalize" again. You can tell that it has engaged because the tach will drop a few hundred rpms. If it's not doing this, a simple trans oil change (with filter) may correct the problem. OD is activated by a shift solenoid on the valve body that may be a bit gummed up.
95's show a shift control module on some diagrams I've seen, but not on others. I read this as a possible "half-year change" So you may or not have one. If you do, I'd check that as well!
