Hi Gary, Great tutorial on installing oversize valve! One tip to make your expensive reamer last is NOT to reverse them. Use a good lubricant and low rpm and one direction of rotation for in and out. Thanks again and your passion for transmission repair is very apparent. Thanks and great job.
Thanks for showing how easy it is to ream out the valve body, tomorrow once i get the parts in for my 4t45e ill be reaming out mine to install an over size valve.
Iv'e had a 2-3 shudder id say for the last 40k. Then recently the vehicle started bucking 2-3 and sometimes 3-4 it was acting like it was going upshifting and downshifting at the same time. I never took a line pressure reading on it but to me it felt like it was loosing pressure. I work for GM so i called gm tech assist and they told me to replace the valve body and reseal transmission as needed. I normally don't work on transmissions and this is my own car so I searched on Sonnax's website and saw the symptom of a 2-3 shudder and to replaced the pressure regulator valve with an over sized one. I'm also replacing the boost valve and sleeve with their updated one. Also i'm replacing the pressure control solenoid and the shift solenoids.
Hi Gary I understand how a bore could get worn, causing the valves not to seal... But what would cause a valve to be binding in its bore? I have the valve body off a 2012 Nissan Altima CVT (JFO11E REOF10A) The ratio control valve, seems to be sticking or binding slightly. Tore it all apart, cleaned it well, and checked all valves. This is the only one that has issues. Put trans back together and im getting a stepper motor code (P1778) But stepper motor specs out good when i ohm test the coils. Any ideas? It has to be the ratio control valve sticking thats causing this... it connects to the stepper motor.
Hi Gary...just a tip to help you out on the calibration of your vacuum gauge which is incorrect. When you adjust the gauge for a reading of 5" Hg, turn the 'PUMP' knob on the right. Once that is correct, block the small hole as you've done and adjust the 'BLEED' knob on the left for a reading of 25" Hg. Repeat the procedure above until you get the 5" and 25" Hg. You'll probably see that you can get the 25" Hg. Take care Gary...
why would only the low/reverse clutches be burned on a 95 4l60e, thanks or more specifically, what valve or section of the valve body controls the low/reverse clutch activation in the 4l60e E?
This is great information and well explained, but on the unit that has the gauge is this something you made or can I purchase this somewhere. Once again thank you for the video it was very useful.
That unit is made by a company called sonnax, they have a website but you may have to purchase the product from a transmission parts supply company. Gary
Great video. But I have the same opinion as Mostafa, if there is oil on the valve body the vacum reading will higer, thus making an incoherent reading. Gary can clarify this? Thanks.
Hey Gary! Thanks for the video man. Is there a way for the next guy that might work on this say in 20 years from now to know that there is a modified valve in the valve body? Also did this fix the trans? Thanks! I'm sure it did but had to ask, LOL!
+ILTSYC Yes it did fix the trans, This valve is redesigned, so if they know what the factory valve looks like, they will know it was updated. Hope all is well, any transmissions your currently working on?
No need another one to work on LOL! I might get a Nissan truck for almost nothing for one of my girls. It needs transmission work. One of our employee's has an 03 F-150 with no forwards gears but has reverse. I haven't offered to work on it, I really need my own scanner before I start taking in transmission work. The Windstar has done awesome! We took it all the way up to the WV mountains last month following our girls church ski trip.\
It's from a company called Transgo, you can go to the website, not sure if they will sell to you. I can always hook you up with my sales rep if you like. Where are you located.
Gary Ferraro Monroe La . I’ve ordered a Trans Go shift kit- 2 and while I have it apart I want to install a new actuator valve to make sure I repair it the first time. Mine is 91 2500 4wd . Thanks for your quick response . If I were near you I’d see if you’d vacuum test it and then repair as need!! Your the man!!
hello sir ,i took apart a mps6/dct450 valve body and a small steel ball fell out of the hole where the csms2 [odd gear pressure solenoid ] on the side of the valve body that has 3 solenoids,the diagram does not show a ball there,sadly i lost the ball ,its about 2mm.Can you tell me if that ball is supposed to be there ,also what is the size of the ball,thank you
Hello sir please help! I want to install an automatic transmission in my car but I don't have the TCU so I was wondering is it possible to control the solenoids my self by supplying 12v to shift gear up and down while driving???????
Well, thats kinda hard to do, i have an interface machine that does that, but just running wires, you would have to supply 12 volts when needed to shift, you would also have to regulate the voltage on the epc soleniod which uses low volts(12 volts too much)
utube now has many videos showing how to manually set up the 4l60e all the way to the 4l80e,manual shift and i used it and installed the internal vaccum modulator kit from transgo and eliminates the ecm entirely,good stuff
well, once the clip is out you could try an easy out, drill the snout and put ab easy out or screw in there and try that, What happened, never had one break on me
P1870 code keeps coming on . Had tranny rebuilt and repaired. New pump. New valve body. New tcc regulator valve. But check engine light keeps coming on i don’t understand and what else can I do to fix . Please help!
4L60E and no just a regular obdII scanner but it’s driving fine after the valve body was replaced but like you said in in video it pops back on after 15-30 miles of driving or so. I think it may just be something simple as a o2 sensor but idk any suggestions.should I just give it time to kinda break all the new parts in and see if it goes away.
@@GeeZee23 ok, couple of questions, How long ago was the trans repaired? the valvebody, was it a good used one. I may have you drop the valvebody and block the reg valve and the isolator valve, i have a video on how to do this, if the code comes back, may be something with pump or converter. The TCC PWM Solenoid was changed?
thanks Gary , I have seen many other videos , but you are the first to explain drilling out valve and vacuum testing
tracycolorado Glad you enjoyed and thank you for watching.
Thanks! Just did this on my first 4L80e rebuild
Good, these bores wear out

+Brad Miller Thanks for the tip and thanks for watching. Gary
+Brad Miller spot on man never run a reamer in reverse i dont even use drill i use a speed brace and take my time
Thanks for showing how easy it is to ream out the valve body, tomorrow once i get the parts in for my 4t45e ill be reaming out mine to install an over size valve.
Whats the problem with the trans?

FINALLY... someone who says SOLENOID NOT SILLLIYNOID...
Pity that iam from europe and product from sonnax are hard to find... i realy enjoy your passion Mr Ferraro. Thank you
Thank you and Greetings from New York
why not just order from ebay?

+stuzman52 Thanks for the tip, i will try that when i get back to the shop
stuzman also keep in mind that the hole on tool used to calibrate is .030 in size,meaning that a 5in vacuum equals .030 size leak
Thanks you very much for teach more video
Thanks for watching
Good test

Your welcome. Gary
I've never done this, and not had a problem.
I had a problem only on a hand full of trucks with this unit, so now i do everyone
Hi gary the valve body must be clean from any oil specially during vacum test .thx for the video
+Mostafa Ameri Yes, i like to have it clean during the process, during the process i use the cutting oil, thats the only oil i use for this
Great video. But I have the same opinion as Mostafa, if there is oil on the valve body the vacum reading will higer, thus making an incoherent reading. Gary can clarify this? Thanks.

+ILTSYC Sounds good, nice to hear from you
You to bro! Do you vacuum test all the time or just when you suspect a valve is worn?
+ILTSYC just when i feel there may be a valvebody problem
Thanks for sharing! Could you supply the part number for the reaming kit?
It's from a company called Transgo, you can go to the website, not sure if they will sell to you. I can always hook you up with my sales rep if you like. Where are you located.

@@ronaldlewis6062 ok, if you need help getting the kit let me know
How do you know what to cover with the vaccum block and where the hole should be when testing each bore?
There are vacuum test guides on Sonnax web site

Does the valvebody have to be perfectly clean for testing?
It should be clean , yes
How do you get a broken shift solenoid out of the valve body on a 1993 4l80e?
well, once the clip is out you could try an easy out, drill the snout and put ab easy out or screw in there and try that, What happened, never had one break on me
P1870 code keeps coming on . Had tranny rebuilt and repaired. New pump. New valve body. New tcc regulator valve. But check engine light keeps coming on i don’t understand and what else can I do to fix . Please help!
Zach Godshalk is this a 4L60E. Or a 4L80E. Do you have access to a scan tool that shows live data
4L60E and no just a regular obdII scanner but it’s driving fine after the valve body was replaced but like you said in in video it pops back on after 15-30 miles of driving or so. I think it may just be something simple as a o2 sensor but idk any suggestions.should I just give it time to kinda break all the new parts in and see if it goes away.
