'95 Jeep Grand Cherokee tranny odd issue.

Alright everyone couple of issues that i am just stumped on. Even after reading most of the forums. Some symptoms match. Others are close, but nothing seems exact. Please help to the best of your ability. Thanks in advance

MY jeep: 95 5.2L engine, Limited edition.

Transmission, I have not actually read the plate on it yet, but my shifter reads, All wheel drive, Neutral and 4 low.

Problem: When stopped at a red light sometimes the transmission engages and bogs the motor down, but then disengages right away (never stalls surprisingly, happens once a day).

Sometimes (random and rare, maybe once a week) i will go to hit the gas and the transmission will not engage, as the revs come down it snaps into gear at about 2k and CLUNK. I get a nice whiplash and gives me a nice jump.

No slipping between gears so i do not think its a bad tranny. However, as i am cruising at 70, it will shift up and down as if it cant tell whether i am on the gas or off it.

Ideas? suggestions? i have replaced the filter and oil. recently no change in the problem. I have no problem going to the junkyard and finding parts. Any suggestion will be taken seriously.

I don't think this suggestion explains all of your problems.. Certainly not the one with the tranny not engaging until 2000rpm.... but some of them could be caused by the throttle position sensor.. I had the downshift problem with my 97 at about 65mph, caused by a bad tps sensor. bad output from the tps can cause erratic shifting, sometime caused by a bad spot that will be seen at a particular throttle position. Good luck in fixing your problem. please let the forum know what the eventual fix is.

TPS won't affect transmission engagement on a 95, its a 46RH trans, its hydraulically controlled, except for overdrive and torque convertor lockup. My trans was doing some of the same things that yours is doing now, and then it lost all forward ranges, gave me an excuse to built up the trans with some stronger parts.

So all these posts i am reading about tcm modules, and speed sensors/tranny sensors can't cause this??

The erratic shifting seems to be electrical common problem on the I6, any common problems on the 5.2??? .
Any suggestions before i rebuild a whole tranny?

The dropping into gear at 2k is so rare its ridiculous. i just stated it cause it does happen. The most annoying problem is searching for gears.

Thanks,

Kris

Ok, let me reword this a bit....

What electronically affects the transmission on a 95 46rh trans?

Basically what i want to do is replace these parts before i give up and spend 2k on a tranny. (just a guesstimate)

I have seen several postings about tcm's, tps, o2 sensors, and such. However, these postings were for 6 cycl and the wj, which i am sure is different.

try the valve body, governor solenoid and kickdown solenoid. You can find a remanufactured valve body on ebay with all these parts included for around $260.00 with a $150.00 core charge(be sure to specify all these parts to the supplier). I would try that first. If nothing else, you can put the new parts in a different tranny from a salvage yard if yours is totally shot.

get the pan off and see if there is metal collected on the magnet, sounds a bit like the torque converter has failed

The 46rh does not have a governor solenoid or a kickdown solenoid. The only thing electronically controlled in the 46rh is overdrive and torque convertor lockup. Heres a couple of pics of my 46rh valve body showing the OD/TCC solenoids on the valve body. 1st, 2nd, and 3rd are all hydraulically controlled. It's a 5.2, not s 4.0 with a 42re.

Don't forget the Sonnax manual valve. Stock on the left, Sonnax PR valve and manual valve on the right.

I usually use the transgo or superior kits on the dodge rear drives
sure cure from sonnax are awesome kits but about 10 times the cost of the others just blows the budget on rebuilt units, for not much better performance

my 93 4.0 was doing the same thing. felt like touque conv was locking up and drop into gear from a stop. I found that i was down a quart of ATF. topped it off and problem has gone. the odd thing is that i cant find a leak?

I found that same problem in my 94 5.2. i would go from reverse to drive and it would stall, i added a quart and the problem goes away, and every so often it comes back but i cant find a leak either.

He should start with the basics, check fluid level, if that's o.k., drop pan and check for metal crap and then check you filter.

I am pretty good with cars, but i have never taken apart an automatic tranny before. Anything i should know? Really the first one i have ever owned.

Oil is at the right level,i'll double check it today. No metal in the oil. the biggest problem is shifting. The others i could live with till they cause problems.
How much of this can be done without dropping the whole tranny?

Past few days seems to be getting a little worse, it seems its at a higher rpm, and having a hard time finding overdrive.

MN natv thank you so much for pictures. helps a lot. I assume those pieces fall down after undoing the bolts above the filter??
