The following has been unsuccessful: Flushed and change the power steering fluid, ruled out the fuel pump located just under the intake throttlebody. I've tentatively ruled out lifters, since the audio noise level does not increase when removing any valve cover openings (oil fill cap, PCV,etc) Just dropped all the skid pans, and the lower belt idle pulley located next to the alternator is wobbly when hand shaken. Now must wait for noise re-occurance to rule out the pulley. Will advise.
I replaced the MR263723 Freewheel Clutch Valve, problem solved! Paid $89 for it at local Mitsu dealer. They actually had it in stock! Took about 45 min to change (I was being very careful with the hoses). I removed the top of the airbox, but not the bottom. That probably would have made it a little easier. I believe it was two 10mm bolts holding in place.
Andrewvw44's pictures helped greatly in locating it. Thanks!
Thanks again all!
Thank you for your Help!!
I have the same problem with my montero truck also(jerkin alot when i drive&the engine light want cut off) i had wanted to know did the 2 cans of carb cleaner really work? And are you having more problems after you put the two cans in? Thanks
i just replaced spark plugs and valve cover gaskests and tube seals (found lots of oil in all the tubes) also sprayed 4 cans of throtlle body cleaner through the vb while it was off i also spayed a few cans of engin degreaser once it was all put back together and hosed it off started it up and it sounded fine as i backed out of the drive way i heard a light thumping sound that that only did it in reverse not in drive i couldnt find what it was so i contenuied on my road test then i got to the end of the block as i stopped i heard the thumping sound again (it kinda sounds like abs when you lock it up but i am fairly positive its not coming form the break system) about a mile down the raod i began to slow down and the nutural light started blinking and the trans seemed to be shifting funny chirping the tires then i was in fail safe it seems from what i have read its seems that the most common remedy is the speed sensors but it just seems kinda odd that it would happen right after i did the above stated work is there any thing that i may have done to cause it to go into fail safe? maybe a crossed vacuume hose? or a missed vacuume hose? the water when rinseing off the degreaser? o i also at one point set a scew driver down on the battery and it touched both posts causing some sparks? is there a way to test the speed sensors? i am trying to avoid paying a shop or the dealer to dignose it because i am just gonna replace it my self any way

Noise from engine when pressing on brake pedal:

An interior view on what happens when I press on brake pedal:

This is what happens when I simultaneously press on the brake pedal:

This is the cylinder that rattles when I brake, I'm assuming this is where the noise is coming from:

Hope this helps, gmguy18. God Bless
I am curious if kevlagirl tried viking62's solution? I was thinking that it may be a clogged AT filter and weak fluid. But after reading so many posts it could also be the speed sensor or as viking62 states the fail safe relay(?). I am going to try the relay, filter and fluid flush. Hopefully I will be able to report back with results. It may not be immediately....
I've had it into two different shops where they pulled the wheels and looked at the brakes and neither shop could find anything.
It's quite noticeable and even a bit embarrassing when backing the car. Given it's my wife's car, you might imagine what I'm going through... :-)

copy and paste that link, don't search for Mr. Tranny :surprise: LOL. I read many of the comments for Dr. Tranny and thought I'd give it a try. NAPA had it for $6.35, and just like all the reviews within 6 miles of driving the torque convertor shudder disappeared!!!!
I bought this Montero :lemon: used and it has plenty of other rattles and shakes but at least it does not sound like I am going off the road all the time. I hope that this liquid mechanic lasts for awhile but at less than $10 a shot I'll put it in every month if I need too .
Good Luck!
