good evening. i am a novice diyer, so giving my opinion. an all of a sudden random misfire screams timing problem to me; ckp sensors are know to malfunction when hot. and a surging at idle points to major vacc leak enough to cause misfire. i suggest to get scan data with actron at autozone...

hello all. can someone please confirm these numbers on the gear tooth counts on this transmission. O/d sun=24t, o/d ringear=72t, fwd ringear=57t interior, fwd sun gear=27t , rear sun gear=25 or 27, rear ringear=52 or 57?? if these numbers are correct, then: Reverse ratio= rear drum/plnt...

I agree. Already decided to do so. Mrs macgyver needs to pick it out. Thanks

Go Haynes! I'm sorry. I wasn't really bashing the Haynes manuals. I actually prefer it over Chiltons. (Wow that IS A BASHING!) I use it all the time for everything else, but I will keep that thought in mind just in case.. my abs is exactly as you described. Thanks for confirming that for me.

suggestion for u Hey FFL. (Hope that acronym was cool to use). Just a wild suggestion here. I'm going to rebuild my transmission soon, and I have the same concerns regarding realignment of universal,mounts,bell housing,flywheel ,BOLTS ETC. I think to spraypaint the critical areas and that as a...

thanks for replying Appreciated the reply.

SORRY! Mis informed! I have 4wabs. How naive to trust haynes manual which specifically says: rabs is for 2wd, 3.0 and 4wabs is for 4wd and 4.0. READERS AROUND THE WORLD=BEWARE!! :-)

In my humble opinion, I'm a firm believer of the addage "IF IT AIN'T BROKE, DON'T FIX IT". OBVIOUSLY, the noise was originating from this joint. Logically, something was wrong. If it was a lack of lubrication in the needles, wd40 is not going to last long. I personally would take it apart and...

So, how did you make out with your diagnosis? Just curious

obtained vb hydraulic maps Great. I'll look that up. I bit the bullet and got a subscription with Mitchell 1 and the vb diagrams are there, but since the directions of fluid flow aren't noted, it's hard to understand what is feeding and exhausting in each solenoid and therefore defeating the...

codes I'm getting C1258 and c1259

My 1996 3.0 ranger is "2 WHEEL DRIVE" with "REAR ABS". Why in the world would i be getting DTC codes for front abs failures? This vehicle doesn't have any. I'm using an Actron scanner 9580. The abs light goes off with key off, and only comes on after i have moved the vehicle forward. The actual...

Hi. Just chimming in here. Did you have the opportunity to just diagnose the no starting with the original pcm? I'm not savvy about antilock systems, but shouldn't the power to starter be cut off therefore not turning over? so if the engine is turning over,there are so many other things that can...

Over 200k. So you mean a testplate to test transmission leakage after the valve body is removed, and not the plate for a wet airtest like sonnax suggests?

perfect, thanks That sounds like the most logical steps to take for this valve body. I'm going to rebuild this transmission anyway. Even though it will be my first one, I'm very confident I won't mess it up. I'm have seen the rebuild diaries and will use them the best I can. Can you think of...

rebuild valve body So brooklyn bay. I would like to rebuild the valve body again. Were you going to suggest a thread or something?

Glad to hear your transmissions fine. if you are still driving the vehicle,my concerns for your transmission would be this: a worn u joint becomes loose which causes drive shaft rattle which might eventually ruin your bushing and seal in your transmission external housing and possibly your drive...

about harness Yes. All the solenoids checked out ohmwise, EPC was about 7 ohms though. I saw a YouTube video showing how to check to see if the solenoid ports are actual opening when energized. I regret not doing that, ensuring proper operation. Just cause it clicks doesn't mean it works...

repaired valve body. Thats a great suggestion. I did actually get my tranny going again after having the initial slipping failures by replacing torn gaskets. It was slipping just slightly after that fix. The valve body was disassembled, cleaned, and I used high temp thread sealer on all the...

hard shifts curiosity Welcome. I'm curious to know if the transmission has been shifting hard and therefore might have been the cause for the ujoint failure, if indeed that's your problem. I would suppose these joints should withstand a lifetime of hard shifts.

so that makes a lot of sense.it can't just be fluid exhaust that brings the servo off the band. Fluid must also push it back.so two of the things that might be causing the transmission to shudder when initially engaging reverse could be 1.Rev. servo leaking, (due to seaIs/bore wear/broken pin)...

thank you for clearing that up. I suppose you must do a lot with newbies. sorry.I now understand that what I was asking for to get these VB hydraulics diagrams might be considered copyright infringement.it's hard to know what's legal and what's not so many pages, pictures and posts are seen on...

thanms Brooklyn thank you so much Brooklyn. I appreciate the reply. So I'm getting many views on my posts but no one else has replied but you. does this mean many of are also looking for these VB hydraulic diagrams and that it seems no one has them or am I simply asking the wrong questions...

I'm trying to learn more about my 4r44e transmission with your guys help.I really need to understand the hydraulic flow and operations of the valve body and applying components better before I drop this pan again. So I'm hoping that anyone here can post these diagrams and their explanation for...

Thank you all sincerely for being part of this forum. You have helped me immensely in gaining knowledge of automechanics, especially in my quest to fix my transmission. Looking forward to picking your expert brains! HA HA HA HA!! SORRY, THOUGHT I WAS DR. FRANKENRANGER FOR A SECOND! See you at...
