It's possible that your transmission needs flushed. I would start with that as it's the least expensive thing to do on a tranny.

Suzuki grand vitara 2000 2lt


lost engine power, or transmission slips????
which is it?
the engine rpm tells you if the engine is weak or transmission slips.
2.0 liter , DOHC I4, J20 engine.
which transmission, my guess A/T box. (sounds like?) sure..
test one
1: in drive. pointed in safe direction, say a field or ?
2: parked, hand brake and foot brake held hard and fast.
3: race engine to wide open throttle for 1 to 3 seconds.
and lift right foot. after noting RPM. quckly.
4: rpm below 2200 rpm is a weak engine , if the engine spools
wildly up to 3500 rpm or more, the transmission is bad. (slips)
this is called the stall test. (in the FSM)
2,300 - 2,600 r/min. for H25/J20 engine
stall test passes. so does the transmission reach 4th gear.
1,2,3,4? yes/ .no.
yes, the its not the transmission.
if engine power lacks in any gear, that is the engine. weak.

this post is about the engine power, (my answer)
will you change 100 more parts guessing?
why do that?, any shop can diagnose it for a fraction of your guessing.

if the trans dont slip
  1. over heating? the engine?
  2. never done a tuneup this decade?> really?
  3. low fuel pressure?
  4. low engine compression.?
  5. Bad MAF sensors or just dirty?
  6. check engine light on running?, why ignore that, scan it.
  7. weak spark , see #2 and 6
  8. leaking or clogged injectors. or stuck on, for 2 reasons.
  9. Intake vacuum air leaks>?


both the engine and transmissions are complex
as is the vast number of tests to do. based on previous tests and logic.
do you want to test or gue$$?

Sounds like it is stuck in second gear. Overdrive only drops rpm by a couple hundred. In third gears you should still be less than 3,000 rpm.

Second gear is a default gear when the transmission is in limp mode. Is the check engine light on? Does it shift if you manual shift through the gears with the gear selector?

2005 jeep grand cherokee laredo transmission shifting problems


  • A/T or M/T (auto or stick, gee)
  • if A/T is this the 42RE box>? are you in DRIVE? or 1 or 2 gear.
  • does rpm rise above 3000 rpm > at your attempt? if not ,its a bad engine (weak)
  • is the shift linkage even shifting correctly (movement top and bottom)
  • check levels yet. (and for pink ./red AFT not black-metal flake
  • change the filter yet? or skip service. at 50k miles. ?????
  • check all fuses yet>?
  • using a basic OBD2 scan tool are there any tranny DTC errors?>
  • does the FSM stall test pass? in 1st.? and reverse?
  • if stall fails, slips , then tranny bad. if not its really stuck in 1st gear.
The TCM commads the gear change, there is no valve body brain.
the TCM shifts to second with good inputs to the TCM
if the TCM sees bad inputs it will tell you, SCAN IT.

I have a 2003 mustang cobra with the 4v dohc v8 supercharged. It idles perfectly. when i rev up the engine it sounds great, but when i take off and get into second and third gear it wont go past 4000...


Check the prongs on the #1 coil to see if it is crackd if it is left alone it will eventually turn to a multiple misfire, also take the coil off to make sure nothing is shorting out.

Cruising rpm even after the OD has engaged has a lot to do with the differential gear ratio and tire size.
There will always be a variation between different vehichles due to that alone.
To see if the OD is working, at about 50mph, lightly touch the brake pedal. If the rpms increase for a moment then the OD was engaged. (touching the pedal momentarily disengages it...good thing to know when hill climbing!

My 93 ford probe gt wont idle and wont shift outa 2nd gear


Sounds like you need to check your vaccum lines for a leak. This is easy to do. Buy a can on carburator cleaner and with a friends help keep the car running as you spray your vaccum lines with the carburator cleaner one by one. If you have a leak it will **** the cleaner into the lines and cause the vehicle to stall out. Replace the line if this happens and continue checking all lines until all bad lines are replaced.
