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
Hiram Gutierrez: This is a late model EC3 valve body on a 4L60E transmission.
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.
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.
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.

destiny johnson: i did the flip on my 2002 chevy trailblazer do I still drill the holes or
should I not drill them?
El Ocho Fierro: Hola amigo para aser ese trabajo se nesesita remover la transmission?
Quitarla? Gracias 2000 yukon 5.3 p1870 y p0712 gracias?
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
Fidel: Am I able to use a 4l60e valve body out of a 2006 avalanche and put it in a
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
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
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..
jystrauss: 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.
Maria Elena Gamboa: Buenas tardes amigo! Con que limpia las piezas???
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.
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.
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!
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.
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,

im on right path or throw in the towel and get
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

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
the tab broke during disassembly. Should it be replaced? Thank you greatly!

Hiram Gutierrez: Ok, I'll get it together. You'll have it soon.
posjoey: i have a 99 chevy silverado and its throwing the p1870 code. but it also
has codes for the MAF sensor and the fuel cap code. if i were to fix those
could i avoid messing with the tranny? i was told take care of engine
problems before tranny problems. PLEASE HELP!!
JUDGERAMBO: Is a full rebuild video available?
Hiram Gutierrez: That is one of the symptoms the P1870 trouble code will cause.
juniorcarterlumber: A new trans. Thanks for any help you may give. And thanks for the videos
SS Maro: Thanks for the vids Hiram!! I got a question for ya.. I recentlly had a
4l60e rebuilt and it only has forward gears, even when its in nuetral it
goes forward. I also have abs,parking brake, and traction control lights on
that wusnt on before.. Can U help me out any? Thanks again!!
Jesus Aguilera: I HAVE THE P1870 CODE SET IN THE HYSTORY. ALSO THIS TRANSMISSION HAS A
REALLY HARD SHIFT 1ST TO 2ND. IS THIS SOLUTION TAKES CARE OF THAT TOO?
bash5995: This is better than sitting in a classroom, you are not only an awesome
mechanic, but a great teacher as well.
gcking70: Have a quick question ,do you have a web site on we're to get the repair
DJDevon3: Awesome videos. You are a real professional.
Hiram Gutierrez: I would fix the P1870 first, you dont want to risk burning your torque
conveter. I have both early and late model valve body vidoes. On 99 it
could be any of the two. Then do the MAF sensor and last your EVAP code.
