If i was you try to refresh the trans before any other wear happens, drop the pan replace the filter (pops right in) while the fluid makes a mess =) and replace with new fluid, substitute 1 qrt. lucas stop slip for 1 qrt. tranny fluid though, and make sure the dot reccomendation is right for your truck, good luck and that should help it unless your having idle air problem, but if it feels like its sleeping do as i advised, good luck and take care, let me know if it fixed it always good to get follow ups =) c ya

Trans wont shift into over drive all the time


an automatic trans will not shift into overdrive if the motor is under loads such as hills, or general acceleration. you will probably feel it kicking in as you slightly release the gas pedal on level ground.

2006 Hyundai Elantra with 2.0 automatic with 111000 miles. Car is hesitating and begins shaking going up steep hills. Problem seems the worst at around 3000 rpm going up hill. The car wont stop shaking...


There's many reasons this can happen, but start simple. Fuel pump may be failing. Usually under load they can not supply the fuel the engine is demanding. (Up hill acceleration is a classic example). change the fuel filter first, if that doesn't not correct the problem, test fuel system pressure. (:

No power when accelerating hard


Possibly a plugged catylitic converter. This can cause to much back pressure and that will cause the engine to run poorly under acceleration or loaded conditions.

Looses power /slips going up a hill.


This is a hard question to answer without more information. If the vehicle has a sensation of slipping it is usally the automatic transmission that is at fault and it probably has to be rebuilt. The sensation of power loss could be from the slipping transmission. Try manually downshifting the trans. to a lower gear when going up a hill and see what happens. That can tell you if the problem is the trans, or the engine,

With normal acceleration the 1st to second shift point should be around 2500-3000 rpm. Most of your shifts under moderate acceleration will take place at this same point or when there a light load on the transmission. Under hard acceleration the RPMs will climp higher due to increased power needs and the computer will shift when less power is needed or the RPMs climb to an unsafe speed say5000-6000rpms (depending on where yours redlines). Also going up a steep hill will raise the RPMs higher and goind down a hill will cause a faster shift at lower RPMs. These can always be altered by an individual owner by adjusting shift points, using performance parts and if you have problems (low tranny fluid/trans issues). Your trans RPMS are fine and will vary depening on how your foot accelerates. The shift pattern should be the same every time you drive slow/medium/fast/, look for changes in those patterns you will also catch a problem early.

98 Subaru Rear Transmission Noise/Slipping around corners


I have the same issue. It is the clutch assembly and the 'duty' solenoid at the rear of the trans that tranfers power to the rear diff. My trans light is also on which is the solenoid. The clutch parts can had after market but, the solenoid is dealer only. I'm rebuilding the entire trans at this point (187k miles).
