i have a 93 1/2 ton 4x4 with a 350 and a 4l60e. the tranny will slip when in od when either shifting in to od at a gradual speed up. or will slip and kinda keep slipping while giving er. only slips everything all other gears are good other than hesitation going into reverse but i think that is very common. any help would be great. im thinking it needs a rebuild but i hear there may be a couple solenoids that might help/

Sounds like it might be low on oil or has low oil pressure. Could be something as simple as the filter seal not being seated and sucking air or a cracked pump seal.

 

How may miles on the vehicle? How often is the trans serviced? Has the vehicle been used for towing or over-heated?

the truck has 266,000 kms. as far as i have ever had it it has not been overheated and all it tows is a rzr side by side. i did just get the tranny flushed and filter changed not too long ago. it slipped a little before flush and got worse after. i thought the flush would fix but it backfired on me.

Flushing a high mileage vehicle often causes more problems than it cures unless the trans has been regularly flushed throughout the life of the trans.

 

Even a properly performed fluid and filter change will not correct a problem (other than a plugged filter). Best case scenario is it will slow down deterioration. If the trans is acting up from anything other than a plugged filter, don't expect any positive change in symptoms. The best that one can hope for is a little more longevity.

 

A flush often pics up debris from the pan and passages in the trans case and that debris can get stuck in the valve body and cause havoc.

 

266K is not bad for 1 trans. This may be a good time to have it rebuilt, before something breaks.

Wavery hit it right on the nail. My trans went along time w/o being flushed and then it started slipping on me. i thought a flush would fix it and it was great for about a year then i hauled a pretty well loaded 12ft Uhaul trailor with her and was buying a new tranny the next week :thumbs:

In your case, it was the miles (and towing) that did you in. If the flush causes problems, it will show up right away.

If the oil is up to normal level then its time for a rebuild.Once it starts slipping theres nothing that can fix unless it is rebuilt.

Not only a 3 year warranty, but a 3yr/100,000 mile warranty. Only sidestep is the near 1800 dollar list price on some of them.

Don't forget to add another ~$500 or so for a new converter. :lol:

Check your Throttle Position Sensor. When mine went bad, I had similar issues in overdrive with my 4L60e.

      I have thought an EV might have some practical value in extending the life of the ICE members of ones fleet. Now....I'm convinced of it. I've been letting my better half access Raven (Mitsubishi Mirage) for her needs while Dizzy has been in the shop. Being the fuel freak I am and given the fact Raven is capable of over 60 mpg in clean air on a warm day I was taken back by the wife's ability to take a car that had used a half a tank of gas that to that point had returned a value of 57 mpg and return in with a decimating 51 mpg for that same tank in that same day in a 15 mile round trip of short hop errands and a stop in the drive through at Micky D's.  😱   Trust me on this. It would take the remainder of that tank driven on the highway to return that tank to just 54 mpg. This is not a Mitsubishi issue. This is an ICE issue that is magnified in vehicles capable of such high fuel economy values. On a percentage basis your 1500 does the same thing. Short hopping an ICE consumes a good deal more fuel and in doing so provides zero additional useable outputs. That entire volume of fuel is wasted in diluting the cylinder walls oil films, creating crankcase moisture and acid content and the resultant wear.    Enter the SLATE. All of that is avoided and the ICE's advantage in range and made useful at reduced wear for your ICE!   Kind'a cool.

      Back in the day people would buy cars based on performance. The charger posted does 0-60 in 3.3 seconds. And it’s fully loaded.  It has a decent warranty and will fit most anyone’s needs. Remember the original Hemi? 90 day warranty. 25K mini truck or that car? I’d go with the car. It wouldn’t fit my perimeter. If I could just talk my wife out of her Genesis. It would be perfect for her.

      Let's pivot this back. Someone said they wanted pictures.   Even better, there's already video. Pre-prod prototypes are already on the road and they're letting the press drive them.   JerryRigEverything did a good review. I really enjoy his content and EV adventures, so I was thrilled when he had the chance to review a Slate:

      The Charger EV was stillborn. Wrong car at the wrong price for Dodge's intended audience. Now at a good price with fire-sale discounts, and still not selling, it's still very much the wrong car. Again, Dodge's intended audience. I believe a lot of Stellantis' EV blunders were all under Tavares' regime at Stellantis...the board convinced him to move on. Neat car, just wasn't received on the level that would sustain mass production.   Dodge is headed in a better direction for its core business. I didn't think there was anything left to get excited about re: the Durango after its 15 year run, but they're just now releasing a 392 version that should price out in the low 40's. Nicely done. I'm not sure I would touch anything Stellantis makes with a 10' pole these days, but the Durango is still mostly parts designed like 3 parent companies ago so maybe it's still OK?
