6L50 Valvebody, No Forward

[@joselemus7190]

Thank you so much for sharing the videos, Mr. Gary. we greatly appreciate you for helping so many people to repair or understand how new transmissions work!!!

[@GaryFerraro]

Thank you very much Jose, I'm glad i could help

[@sethsoileau8257]

Awesome video, very informative. Will be looking into my 6L50 this next weekend. Very similar issue, slowly engages in 1st, then shifts through normally. Never a problem with reverse.

[@JoseLopez-en6vt]

Good video I fix my gmc problem with this video thank you save me lots of money!!

[@Benjames885]

Great video mate. I’m in Australia and have a Holden Colorado with this transmission, and only recently been showing the same issue (however intermittent).

[@GaryFerraro]

reverse is no problem?

[@bonzaibarty]

Good job! You are very knowledgeable!

[@phelon99]

thank you you saved me a lot of money

[@billwilliams4877]

Gary, why do we see so many torque converter problems with the 6l50 in gm vehicles but not with bmws (6l45)?

[@GaryFerraro]

Very Good Question, not sure unless BMW is building there own for there cars.

[@billwilliams4877]

Makes sense. The 6l45 was produced in the power glide plant in Strasbourg France, not the U.S. possibly the computer programming as well.

[@JediShilts]

Bmw owners service there cars bmw shop, prolly ain't pulling to much I reckon

[@m3mhunter]

Hello, can you provide a pic or diagram of where the checkballs go... my sons CTS seems to be having this issue and I'd like to tackle it with him.

[@garyhoffman4653]

Great work'

Pretty nice impact driver.

Gary, I have a 2003 Jaguar S-type with a ZF6HP26. I recently changed the pan/filter and used Lifeguard 6 that fixed the 1st gear lurch at stop, but I still have a problem with 5 gear shifts. The transmission will go into safe mode usually the car will be hot when this happens.

[@GaryFerraro]

Your rear stator bushing is probably worn out causing a leak in the E clutch apply oil, E clutch is on in 4TH-5TH and 6TH

[@skutahuniai4830]

So did that check ball actually "shrink" or is it just worn out from moving around repeatedly on the separator plate? Shrinking of a solid pellet seems a bit questionable.

[@GaryFerraro]

i'm sure it's just worn out, and shrinks in size

I have a question concerning the 62te transmission. I have an 09 journey sxt 3.5 motor 6 speed transmission. Ok. The first trouble I had I was driving down the highway and the transmission went into neutral. I pulled over immediately and called triple a and had it towed home. Put a quart of tranny fluid in it and it did perfectly. Several months later the side pan rusted and poured tranny fluid. Immediately stopped driving it and had the pan fixed. Put it all back together and I can drive around the block and it goes thru all the gears perfectly but after that it won't shift at all. Please help me.

[@GaryFerraro]

Hi Lisa, Has the car been scanned for codes? Would you say it works good for about 15 to 20 minutes and then gives trouble Or stops moving?

[@bassamghaferi3723]

Mr. Gary ,, Do I have take the whole valve block down to check the check ball ?

[@GaryFerraro]

remove the valvebody and take it apart

[@mahmoodagha2794]

Sir great job no one is perfect, sharing of experiences is carrying with each other to out fake mechanic world of car market to safe customer tension money time, request is that if exchange number with each other

Hi Mr Gary. I have a VW phaeton V8 with ZF6HP19 GUW and it seems weird for me. Car has only 99k miles. U guys are familiar with this transmissions? Thank you very much

[@GaryFerraro]

Just did one in a Phaeton

[@damiantowner7358]

Just curious if a missing check ball would causes bmw to go into trans failsafe prog?

[@GaryFerraro]

what code or codes are you getting?

[@zukremix]

Did you reuse the old body gasket or installed a new one?

[@GaryFerraro]

reused it

[@redwillsdiychargedupvideo1486]

This was an amazing video I have a 2007 Cadillac S which I believe has the same transmission How much do you charge for this service

[@GaryFerraro]

4.6 motor

[@geraldknorr]

I have a 2016 GMC canyon truck down shifts hard in low gear.and when I accelerate it bucks in low gear. 2.5l rwd 6L50 transmission

[@GaryFerraro]

any codes?

[@phelon99]

whatif you find a stuck check ball replace it with upgraded check balls and now no forward or reverse i had reverse

[@GaryFerraro]

Retrace your steps, did you hook up the manual valve?

[@automaticosdovale-cambioautoma]

Very good!

[@randyng-a-fook1695]

Good day. What brand and type transmission fluid do you recommend for a Chevrolet 6L50 tranny? Thanks much

[@GaryFerraro]

you can use Dextron 6

[@randyng-a-fook1695]

@@GaryFerraro what brand is your preference?

[@GaryFerraro]

@@randyng-a-fook1695 You can get the Dextron 6 from the dealer

[@randyng-a-fook1695]

@@GaryFerraro thank you very much.

[@mikeholmstrom1899]

I wonder how many crooked shops would just sell a full overhaul for this issue? How does the person who sent the VB to you do a relearn with the rebuilt valvebody?

[@GaryFerraro]

No Relearn needed, He called me and said worked real nice

[@redwillsdiychargedupvideo1486]

2007 Cadillac SRX with no forward It'll go for a few seconds and then just drop off but I have full reverse literally drove the truck backwards around the corner to park it properly lol

[@GaryFerraro]

[@redwillsdiychargedupvideo1486]

@@GaryFerraro Yes I have the V8 motor

[@GaryFerraro]

@@redwillsdiychargedupvideo1486 ok, that should be the 6L50, either the checkball has shrunk down or the 1-2-3-4 piston may be cracked, checkball more common problem

[@phelon99]

i forgot to say 2017 colorado diesel with 6l50 100.000 miles trans very clean inside

[@gmcyd]

I had the forward go out on a 15 Escalade as I was driving.the Reverse works fine fluid level is good and clean never had previous transmission issues is it possible I can be this I called some shops they all want to replace the transmission without even seeing the vehicle If you could help that would be great

[@GaryFerraro]

You either have a bad check ball or a cracked 1-2-3-4 piston. I would pull that valvebody and look at that first

[@gmcyd]

@@GaryFerraro thanks!

[@GaryFerraro]

@@gmcyd See if there is a shop that will look at the valvebody first before doing the trans to see if the checkball shrunk down. Where are you located?

[@gmcyd]

@@GaryFerraro I will I’m located in San Jose ca most I’ve asked just want to replace transmission btw I forgot to add it had no check engine or warnings on dash

[@GaryFerraro]

@@gmcyd still could go either way, check ball or piston. Are you familiar on how to drop the valvebody?

[@gigimarfa877]

Is this possible to happen on an 6T40 Gen3 trans ?

[@GaryFerraro]

I never had a gen 3 do this, had a few Gen 2, but i don't see why not. I would say either a clogged solenoid or bad 1-2-3-4 piston, does the car move in manual 1?

[@gigimarfa877]

@@GaryFerraro no, but when I switch from M1 to M2/3 car Rpm drop like it wants to stall but won't stall it acts normally after - and still no movement

[@GaryFerraro]

@@gigimarfa877 Well, I would try a tcm first, can be done without pulling the trans or if you can get solenoids separately, it would be the on/off solenoid

[@gigimarfa877]

@@GaryFerraro many thanks

[@phamuchuynguyen7921]

❤❤❤❤❤

[@rtz549]

Can't believe they put the computer IN the trans like that.

[@igotaction]

When all else fails with your transmission, just pull it and send it to Gary, problem solved.
