I can see them just fine. Where would I get the gauge to do this test and or the attachment.

 

That I cannot answer. It's not a procedure I've ever done, unlike posting screenshots, I've done plenty of those.

 

In my case, I made an auto trans pressure gauge with a 0-300psi gauge and 6ft of hydraulic hose, the fitting size is stated many times in the Archives, so you obtain an appropriate fitting with 3/8" barb outlet

either via Ebay or Hydraulic supply place

Or you can buy a pressure test kit

If you do it the first way, you can leave it and put a cabin mounted trans temp gauge in place

In that case, where it is very hot, heavy towing, or wheeling, one can give the trans a rest if it gets too hot

I have not used this on my XJ...imo, if pressure is too low on a high mileage trans, the main pump will probably be worn, meaning a rebuild

 

So I replaced the solenoids and still no change I performed the stall speed test and it seemed right range. I talked to another guy that had the same problem. His was the tps sensor. Should I try this?

 

that would be an entirely reasonable thing to try, but you do need a good brand, which gets a bit expensive...at least you will have a spare

I think the only other sensor that can affect shift speeds is the VSS (speed) sensor, and that may also go faulty

some people feel the parts canon is too expensive, (but this is what most non-dealer mechanics would do)

obtaining OEM sensors from wrecks can be more economical

 

What would be a good brand? Omix ada?

 

I forgot to mention that last winter it was having the same problem but it also had idle issues and would shutoff. I replaced the sensor with one from a wreck. It fixed the idle issue but not the late shifting. Everyone tells me that it is electrical and not mechanical if it shifts fine with the tcu disconnected. Which in my case is true.

 

By "late shifting" do you mean it's slow to initially engage when you first put the shifter in drive, or it's not upshifting out of 1st gear? A bad TPS can cause shifting between gears to be early or late. It will not cause slow initial engagement when you shift from Park to Drive. The TPS is easy enough to check with a meter before you drop cash to replace it. Besides the TPS, shift cable, and bad solenoids, the other possible sensor that could cause no upshift is the output speed sensor (ie the trans computer doesn't know you're moving). They usually don't go bad and I doubt it would be intermittent or temperature dependent.

 

Ok so here is all that has happened. I have replaced the tps and solenoids. I have refreshed the grounds. I have inspected the valve body and done all the tips as suggested by others above. Still no change and experiencing the same thing. I have run out of options but am hesitant to get a transmission because it shifts fine manually. I’m thinking the transmission is just going out because it started as a problem dependent on temp but now is gradually getting more and more.

 

Very frustrating because I have read a ton of other forums with people having the same problem and almost every one of them it was fixed after replacing the tps twice or more times.

 

maybe I am confused, but as previous poster lawson enquired, I am not 100% sure exactly what your symptoms are ?

more description is better than less

does your high shifting shifting issue respond to throttle input ? (mine did)

I would swap a speed sensor before swapping trans

 

The problem would only go away when revved very high for a longer period of time. I don’t think it would be the speed sensor because it’s only dependent on how long it sits or the temp outside. I had the same problem last winter/fall. When I first put it into drive it moves but when I get going it does not shift out of first gear until revved for while at 4500 or so rpms. Then it will finally slide into gear. It will do it at all rpms so the speed doesn’t really seem dependent. Last winter I remember in the cold mornings it would also feel like it is not engaged when put in drive. I have a stronger feeling that it is something internal dealing with fluid and or wear because it has gotten worse lately even in warm weather. Feels a lot like a pressure issue the way first gear seems to finally “slide” into 2nd.

 

so my symptoms are, after it has been sitting or cold out will not shift into 1st unless driven for a while. And if I stop at a stop sign it will do it a couple times until warmed up. Lately sometimes I will also get a feeling of not engaging into drive when out into gear.
I have replaced the tps 2 times
replaced solenoids
Changed fluid
checked valve body
adjusted kickdown cable
cleaned all grounds and connections
But when it warms up it functions fine. Also let it be said that this jeep is sitting on 35s and a lift and has seen its days in mud and water and been pushed.

 

I would perform the following actions;

*commence searching now for a replacement trans...always much cheaper than if you need one urgently, getting one from the same year is easier etc

* make a trans pressure gauge $20, or order one up, about twice that, measure trans pressure

* when you get spare trans, swap VSS

They dont last forever, so a spare is good

I would also get the TCM thrown into the deal...I got a couple for $40 each..I would replace that too

In the meantime, continue on motoring

 

I sourced a spare trans that is in good shape for $160. I will probably be swapping it in when I get it as I want to have a reliable rig for the winter. I will grab a tcm and vss to.
