No communication between TCM and PCM trans wont shift skips 1st to 4th


An open or shorted condition detected in the transmission 2-4 shift solenoid circuit
did you leave out other DTC's and if yes, why?
you said no comm. so.......??????


Possible causes
- Low transmission fluid level
- Dirty transmission fluid
- Faulty shift solenoid valve
- Shift solenoid valve harness or connectors
- Shift solenoid valve circuit is open or shorted

so what is your question, the A/T is one of the most complex and finicky devices, ever created (puplic) and has 100s of parts.
what is the question.
1: want us to guess>?
2: want us to advice DIY , tests (100s of pages in FSM read it)
3: or? what shops are best?
or?
I can tell you that the FSM covers all this and if really a DIY serious guy and all that,,, ready to buy tools , ready to do all tests.
then RTM, the FSM cover this , see sections on
ON CAR A/T service and Diagnosis.


but first clear the code with any scan tool and see if it comes back
also transmissions have limphome to, and they do skip gears.

one easy test, is the check the solenoid coil resistance.
infinity is bad.
its in the book.
do not fail to post all DTCs and not fail to drive 20 miles, agressivly
to see if the DTCs throw. use a scan tool to see ALL DTCS.
the CEL lamp is near useless. (its for smog)

When I shift car into reverse or drive it will not move


When you're ready to pull off, be sure the emergency brake is off. Be sure the transmission fluid level is in the OK range to drive.. If neither of these suggestions works for your situation, give sequential information... pick a quiet time to set the parking brake, crank the car, put your foot on the brake pedal, shift into reverse careful to listen for what you can hear and also what you feel. foot still on brake pedal shift to drive. again what do you hear and or feel?

I have a 1991 GMC Sierra 1500 with a 5L V-8. The transmission is nit shifting into 3rd gear from second properly. Also the rpms are high from 50 km/h to 90 km/h when 4th gear engages. When scaned the code...


My truck had a shift problem from2nd to 3rd. I was ready to buy a solenoid package for it. ( which is what you have to buy, you can't get the solenoids by themselves, several hundred dollars) Someone recommended tranX to me. I put it in and within three days the transmission quit slipping, it's been over two years now and it hasn't missed a lick. It was a ten dollar fix, compared to $300.00 that the package was going to cost. not including any labor to install

Hesitation in Transmission Shift


The ES built form May to August 2006 had a faulty valve in the transmission. Lexus voluntarily replaced over 700 transmissions as good will while seeking out the problem.
Once discovered the valve was replaced in production beginning August 2007. Your production date is on the drivers door pillar. Later models were fine however some transmissions have been reprogrammed to adjust for a shift issue. My Sienna , lags and then shifts late and hard sometimes upon acceleration from a stop. Similar transmission, same fix is available. Remember that a problem they can't replicate is always tough to fix, but if this sounds like the same shift problem, ask then to keep the car overnight, you'll get a loaner and they can try it cold. The transmission can be reprogrammed again... Lexus can and will help../.It is in their MOTTO,``we can, we will..."The relentless persuit of perfection.
Post back with an update and your production date

1996 Dodge Ram Transmission shifting problem


I had the same problem with my 96 Ram 1500. I thought I was going to have to pull it out and get it rebuilt or just replace it. That was at 134,000Km it's now got 210,000 and shifting like a dream. What I did to solve the problem was this, as follows:
1. No lucas transmission Fix makes things worse.
2. Get your self a new transmission filter and gasket
3. Grab Gunk transmission medic 12oz
4. Grab 7 Liters of Valvoline ATF+4 transmission fluid (Made for chrysler transmissions)
5. Drop the trans pan and drain all the oil, clean pan and magnet
6. start truck for 5 seconds and the pump will pour out another 1 liter
7. re-install filter, gasket and pan, then add your Valvoline ATF+4
8. Add, the valvoline, transmission medic and make sure you have the right level of fluid

That solved my transmission problems, instantly it was shifting better, I no longer had to let off the gas to make it shift. Now if you have large pieces of metal on the magnet, and it's totally covered in filings, you might want to consider rebuilding the trans. My magnet had usual clutch.         

Anyhow good luck, let me know if it did the trick for you.
