Hiram Gutierrez: This is a late model EC3 valve body on a 4L60E transmission.
William DeCoursey: Hey Hiram.. awesome vid! I have the 1870 code on a 2000 Blazer 4.3. TCC
engages and disengages between 60 & 75mph. Now the trans is asking for max
pressure and my 1-2 shift has gotten a little harder under throttle.
Just doublechecking. 1) I stand a good chance of solving this with the
TransGo 4l60e kit? 2) In a 2000 Blazer 4.3 I do not?? want to bore out the
TCC hole in the separator plate? 3) I do, or do not, want to need/want the
FitzAll Plate & Ball Seal part?
I would never have dreamed about trying to tackle this unless I'd come
across your vid. Beautifully done.
IROC TWAN: Thanks i do the valve flip on all the 4l60-e i do
Thomas Cruz: am taking on my 99 TA. ordered atsg book last night. am researching parts
now. I found your videos and am downloading all now. lost 2 and reverse
after hearing bang when leaving stop light. that was 1 month ago. my
mechanic had it for 3 weeks and had not started it yet. after retrieving
car I found out that he was going to put a bandaid on it and call it
rebuilt. I lost a few hundred in the process, this will be my fourth
tranny rebuild, any thoughts on parts or upgrades. I do believe you are
just down the street from me as I live in deer park. wish me luck on my
xmas present to me.
Luigi G: Hiram I have the same code P1870 on a 4L80E late model. What do you
MAXI MAX: Awesome tutorial Hiram. I have a delayed 1-2 shift followed by a harsh
shift to 2nd on a 2004 Tahoe 4L60E 2 WD with 88k miles. It has no no check
engine light on. I had it scanned and its got no codes stored.
Do you think I might have this same issue even though it's not showing any
trouble codes ? Some one else had suggested that it might be a broken
spring from the 1-2 accumulator. I bought a pinless alinum accumulator
Hiram Gutierrez: +blackericdenice if you have a trailblazer, I don't recommend to drill the
holes. It will make it feel like an extra gear. Just do the valve flip. On
the late model valve body video I have. I have 2 videos on the same valve
body, early and late. Yours is an EC3 Valve Body. Go to my channel, follow
what I have there. 4.9L don't drill...5.3 or any other engine drill. But,
if you're comfortable with the TCC feeling like another gear, that's
SombraLocs: I have a 2000 Chevy S10 pickup truck with 175,000 miles. The "Check Engine
Light" just recently turned on and is throwing a P1870 code. What do you
recommend me do first?
Dirk Smithson: I flipped that converter clutch valve around like you showed. Its alot
stiffer than the other three valves, is that okay? and also would a 3/32
drill bit be okay to use since it's equivelent to .0938?
You said in the video It calls for a .096 but you use a .092
انس كناكري كناكري: شكرا لكم
blackericdenice: I rebuilt a 96 Tahoe trans 17 months and had a 3rd gear flair. The problem
was the new separator plate I bought. I needed to drill the 3rd apply hole
out larger. The flair is completely gone.
JS Watson: Thanks for your videos they have help me a lot! But had a question for you
i've done a couple of 2003 model 4l60e transmissions that I've had an issue
with it going into third gear just from 2nd to 3rd once it goes in to 3rd
it's fine just slips for a second going into third and it downshifts from
fourth the third no problem any thoughts what that might be?
PINNKY: hola hiram ,te felicito por todos tus videos,, eres un profecional.,,
tengo un 2000 chevy Silverado 4.8L,, hace un par de dias empezo a brincar
de primera a segunda,, depues de corer bien unas 40 o 50 millas,, me dio el
codigo p1817,, mi pregunta es,, se puede remplazar la valvula tcc,, sin
necesidad de bajar la transmission ?? o la caja de valvulas ?? gracias.
Toni Stroder: I hope you might help me i am trying to replace my transmission in a 2005
gmc envoy xuv 4x4 4l60e 5.3 motor i have everything apart but it seems to
be stuck right above the starter area it will not seperate from there did i
miss something please help anybody
destiny johnson: i did the flip on my 2002 chevy trailblazer do I still drill the holes or
should I not drill them?
Matt Mckinney: when he fliped that valve BLOW MY MIND !
czhou57: Great video. I had a tcc shudder during lockup, and installed transgo SK
kit to fix this problem. When it switches over to lockup, it now locks up
hard like a 5th gear but it still shudders/chatters. It makes the noise
like a manual car was started in 4th gear. When it locks up at 45, chatter,
shudder, hold down the throttle about 3/4 and it kicks it out of lockup and
accelerates to about 65, then locks up again without any shudder or
chatter. On the scan tool it doesn't notice any significant slip during the
lock up chatter -10 to -20 rpm. Holding the brake pedal lightly while
accelerating, the chatter goes away. I've installed the shift kit exactly
to all directions: replacing springs, adding shims, enlarging feed holes,
etc. without skipping any steps, and added a corvette servo and new transgo
plate. 1-2-3-4 works well outside of the 45mph lockup. What could be wrong?
Burned converter clutches? Slipping band? Even more excessive wear on the
VB that the shift kit didn't fix? This is on a 96 Astro 4l60e AWD. I've
replaced most of all the ignition components recently, and fuel trims are
steady during the shudder.

El Ocho Fierro: Hola amigo para aser ese trabajo se nesesita remover la transmission?
Quitarla? Gracias 2000 yukon 5.3 p1870 y p0712 gracias?
steve rohaley: Really good video man. When I rebuilt mine I left the valve body alone.
Mistake. Going back in it this week. Good info
jc mcdaniel: I got a 97 chevy c1500 with the 4L60e and I get the p1870 code after I
drive for awhile say 25+ miles and then I get a hard shift from 1st to 2nd
and it's also running at 2100 Rpm's at 70 mph and it used to run at 18-1900
at 70 is it gonna be the valve or a solenoid if it's the valve how much
does it cost to get it fixed I'm in Houston tx
J Strauss: Great job, Hiram. Where are you located? I'd love for you to do the work on
my 2002 Blazer. Got a P1870 with some slipping and some jerking. My
mechanic says I need a full rebuild but after seeing you I'm not so sure.
Any chance you can do my work? Where you located??? Thanks so much.
Buddy Holbrook: Your transmission repair videos are very informative and very professional-
Thank you for the time you spend doing them... I am an Master ASE tech but
not too much auto tranny work- about to take on my 2000 Trans Am Ls1 with
4L60E. I believe I have 3-4 clutches bad- get a funny shift almost like
going into the same gear even though I feel the shift and then eventually
get to 4th. Any tips beside the valve flip and hole drilling-going to
change out cam for a bit more performance-staying stock pistons and chip..
Maria Elena Gamboa: Buenas tardes amigo! Con que limpia las piezas???
george thibert: hi love the videos but I have a question when your driving and just lost
all gears in 2004 gmc envoy how can that happen if you can explain thanks
RagingWhiteman: Have you had a plug in the valve body that holds the valves in be stuck and
not come out when you remove the clip? My plug is stuck and will not come
out. The back part of the plug groove is catching. What can I do to remove
it so I can clean the valve body? My 4l60e trans is a 1995 4x4. Thank you
and your videos are a blessing.
ryan butler: I have a 2000 chevy truck that doesn't shift into higher gears. I have had
the transmission rebuilt and just replaced the wire harness/ tcc solenoid.
It will take off strong then I loose all gears.
blackericdenice: Its been 3 months after the valve flip and all is cool. I now drive with
the trans n 3 n the city because the tcc put the rpm to low. If I was to
flip it back around, do they make a stronger spring for the 04 Trailblazer.
I was thinking about putting a ball or something between the valve and the
spring to make it stronger.
Tomasito Gonzalez: my car is not locking up, and the p1870 came up. would doing what you did
fix that problem of the trans not locking up??
DoubleChinRooster: thanks for the video. some stupid Mexican sold me a Jimmy with a hard 1-2
upshift that I did not notice when I test drove because the transmission
was cold. why the usa is an ally of mexico is beyond me.
DEATH TO MEXICO!
blackericdenice: Why did you drill into the plate?
blackericdenice: My 04 Trailblazer jerks when ever it's time for the tc to lock up. Don't
have a code but plan to try your fix this week end.
Rex F: What type of WD-40 are you using for lubricating the valve bodies? Just
regular old WD-40?
Roxies Poxon: Hi Hiram, I just watched both teardown and rebuild a couple of times and I
don't see anything about the park paul removal or install. Do you have a
seperate vidio for that or is it just a no brainer? Just wondering. Thanks,

William Scherba: Hiram, Thank you for this video, my 2000 Firebird is giving me P1870, I
know i need to work on the valve body but do i need to install a whole new
body of just the TCC valve, How much of the above work needs to be
performed to replace just the TCC valve with a sleeve?
Hiram Gutierrez: Yes, its comming.
Flavio C Velasco: have you repaired an A4LD?
Keenan Kaufman: i got this code on my 97 blazer, but i dont feel anything wrong with the
tranny, no slipping or hard shifting, what could this be?
KeshkaKotera: Hiram, Thank you for going through the trouble to create this video and
share your knowledge. I just returned from a 700 mile trip (first long trip
in my little 1998 Blazer I purchased and rebuilt from a wreck) So far I
love the little critter but during the trip she threw the P1870 code
several times. I am relieved to see that the repair is so strait forward
and does not require the removal of my tranny. You saved my bacon! Thank
Quinlan Shanley: How much would it cost to have a repair shop do this?
Nick Brittenham: Excellent videos, where was this video when i did my first 4l60? I'm
starting my second one now and your teardown video was so helpful. Keep up

backing plate retainer ring grove in the input housing. My input drum has
one tab broken off. Only prob with the transmission was 2-4 check ball
stuck in separator plate-caught it way erly and no other damage. I think
