4L60E P1870 TCC PWM Valve Fix WITHOUT REMOVING VALVEBODY

In this video I will remove the TCC PWM Valve in a 4L60E and replace it with a block off valve WITHOUT REMOVING the Valve body from the transmission.

UPDATE: This fix has been working flawlessly for 10k miles so far in this same transmission.

Made a very quick and simple job out of a job that could have been a nightmare. My truck is back on the road!!! Thanks for the video!

Thank you for your informative video. Just did the job on an 1997 Astro van, which was diagnosed “new transmission”. I bought the van without really knowing what to do, but then I fell over your video! So far it works flawlessly. The job done on the back with oil dripping in your face isn’t fun, but its doable! Thanks again, man! I’ll ask if I can link to your video, from a short video I’ll make on my channel?

Thanks for making this video. I’m getting ready to tackle this project

Thank you for your help. I got a p1870 code, also when the tranny gets heated up I get a heavy jerk from 1 -2 gear. All other gears are fine. When the tranny cools down it doesn’t happen. I understand that this might help with that. Just wanted your thoughts. Thanks take care god bless.

Wow! Thank you for this tip! (And the 10k update)

Thanks for posting this video. I spent a tremendous time with this problem over several months, during which time, I had ordered this part and returned it. My main issue with it was that it comes with a rubber seal. If someone is planning to keep the truck for just a few years, now problem, but if the truck is a keeper for the long run...
...then this rubber seal is a major concern to me, as some day it will start deteriorating and thereby sending micro particles in all the other valves.
By the way, the rubber seal did not even fit properly. It was far too big. Yes, I could bring it through the outer bore, but it would have to pass other sharp edged bores, where it would be potentially cut up. So verification that this seal is not cut up during install is THE MAIN REASON for not doing this on the car. In fact, I think doing this on the car is taking chances. Again, once these rubber parts start floating around the valve body, all bets are off.

This still took me 4.5 hrs laying on my back in the driveway. I just suggest to everyone you get the new valve body and separator plate gaskets and some trans gel for the check

be nice to show parts removed and installed since the camera was aimed at the repair

I finall started my first swap. 03' Crown Vic Police Interceptor Ls3/4L80. Im only doing the Ls3 cause i found a Ls3 block cheap. Otherwise it would be a 6.0L. Lol. I dropped the block off last week to the machine shop to get honed or bored. Not sure yet waiting to hear from them to see which. I already had a 40k mile crank and Gen 4 rods and pretty much everything, but the block and heads. It was from a 20q2 Ly6 6.0. Even the accessory braket, intake everything. I still need to grab a set of heads for it. I watch your whole swap. Just curious how its doin.

Well I've been prying on mine for 2 days and I'm starting to think it's impossible to get it out that way

It's funny that you didn't do it on video

[cutterharris]

What year model what the transmission you were working on? I have a 2000 s10 not sure which tcc to get. There’s 2 did numbers with same year…

[GrandPitoVic]

How is your stang doing with the Ls swap brother?

[billy-sxwx]

Im not getting any codes for the transmission. But intermittently when in lock up 40-50 mph my rpms go up and down 200-400 miles per hr. Should i try this before a TC?

[ooorah]

I have a 1994 which I have heard is NON PWM and should not worry about converting this valve? My transmission fuse blew when the weather was really hot. So I am getting ready to drop the pan and replace the Master wiring harness with switches and solenoids.

[montecarlo]

I redid the entire transmission and still 1860 code it’s on the truck side any ideas?

[johnniegregory]

Got it but question how many quarts of transmission fluid do you put back in after replacing the valve from dropping the pan I'm trying to know the exact amount so I won't overfill thank you

[panchovillajuan]

Where did you buy that flashlight from? Nice video i am in the process of swapping that TCC valve as well.

[shellytorrao]

Did you put the spring back in with the new valve

[RonaldMcDonald-fj]

I am getting this error code. The problem with my truck is it wont shift into the next gear as speed is increased. Will this fix my problem ?

[travisgrimm]

Pretty certain my torque converter is on. It'll stall the engine when I put it in gear so we'll try this before it goes to the shop
