4L80E Reverse Servo Pin Fix How To + Boost Test Drive | 7875 Turbo 5.3 LS Bagged S10 Wrenching

[@rowlandhamlin2649]

My reverse got progressively worse over a 4week period. Finally reverse was gone. Shops quoted $1500- $4500.I used crude measuring method . After having a shop weld 1/4 inch to filed it down . End results I added a total of 3/16 inch. Works great no slipping, no hesitation into reverse . Great video. Thank you!

[@Le_Comte_de_Monte_Felin]

The tip at 5:00 on measurement was worth the price of admission. Much easier than fabbing up a dial caliper mount / purpose made tools.

[@philketterer8114]

FYI: If you're just repairing the reverse servo pin you do not need to remove valve body. All you need to do to access the last bolt is to remove the solenoid blocking access to that bolt. Much easier than removing valve body. However good advise on welding the pin. About an 1/8 of a inch is usually good.

[@forevertools67]

Yes, you don't need to remove or even loosen the valve body. Remove the solenoid to access the bolt. I would add, that to then remove the servo, use your fingers to pull the piston into the cover, to allow you to slide it all out from under the corner of the valve body.

[@AbsolutelyNot12345]

If you file just a tiny bit of valve body and the accumulator cover it will slide in and out as long as you remove & install piston with the cover together.

Love the Vette style dash in the spinten!

[@SPPTVarmy]

Its a 55 chevy dash

[@TurboV8boi]

I put a new band in mine and it seems like the pin I have is too long... I haven't measured it quite yet but when I tighten the cover down the output shaft doesn't really turn anymore. Thanks for the vid, this helped me in 2024

[@BlaserBuilds]

Good stuff, glad it worked... Smoked my 80e at the track Friday.

[@SPPTVarmy]

That sucks

[@HotRodDave]

Good info I am about to do the same thing. I have a 5.3 with a lifter tick and tried the marvel and flushes and it always came back. I switched to 0w30 and the lifter tick is gone and it hasn't come back for a few weeks. Wish me luck on the 4l80 reverse

[@austindoud273]

Do you guys gave any luck like at all

[@19815389]

Love that truck Man you have done amazing build, we just need to paint it great job on the trans fix

[@OCALLARM]

Congrats on the trans.

[@1987grand]

Great vid, keep them coming!

[@dragbikedemon]

I would definitely get in trouble in your truck! Lol Looking good Rob!

[@DarkKokoro84]

Wo0o0o Rob show some enthusiasm! xD Nice Happy you got er fixed up.

[@rajcam80]

Awesome! I too now have reverse in my 01 Silverado HD!

[@elkakotas2676]

I have a Chevy express 3500 no reverse but other gears work good

[@aidanrussell-smith4619]

howdy, great video! i have the same issue and am trying to measure the piston thing length, was the outer piston piece flush with the back of the trans housing?

[@Sesha505]

Did you go forward when I'n reverse

[@rpturbo]

Now I am going to have to do some digging. I do not have any of the accumulators in my 2006 4l80e. Mine has the jakes delete, so I am guessing, it was the valve body. At least it's fixed! I've used Marvel in the past, lately, I've use Z-max.

[@jam79car]

Nice to see a Manitoban on here

[@willnotcomply5420]

Rob, we all know Randy fixed it.

[@SPPTVarmy]

Lol. Seeyah or rather read ya in a couple hours :P

[@wademunyard9026]

Hi there. I haven’t watched all your videos but did you check the base circle of your cam? If you used the sloppy stage 2 aka Elgin 1840p then it’s like 3mm smaller base circle

[@christianobellio7111]

You are pretty good on gas prices , during the summer premium over here is like 1.62 euro per liter.

[@DanMcD80]

What year is that trans?

[@DanMcD80]

If a 97/98 I have GM service manuals at the house I can look at the pin clearance specs if you want

[@QdotRich]

@@DanMcD80 what's the specs?

[@SPPTVarmy]

Its a 2008

[@nextlevelbaja9981]

Nice work. Very informative

[@damonens9478]

Was your reverse slipping and then the truck moves?

[@SPPTVarmy]

Yes

[@damonens9478]

@@SPPTVarmy and it was your pin? Cause every transmission shop I've talk to said they have never heard of that in their lives

[@SPPTVarmy]

Ya that fixed it, its a common 4l80e problem from my research.

[@kevinnearhood641]

Do you have a muffler? If so what is it? Does the tail pipe exit in the stock location?

[@kevinnearhood641]

??

Its a dynomax you can see it being installed in this video. kzbin.info/www/bejne/pXKsiJmpZ7RomJY

Totally didn't know it was on air aride 😄 I subscribed

[@bobfalfa76]

I actually learned something from this, thanks Rob

[@MrBeezweeky]

Sounds Great. Love s10s, even more if they have a v8 under the hood. They should have come from the factory that way.

[@6bt_str86]

I'm certain your "lifter" noise will persist due to the aluminum block (just as most LS1's were plagued with)

[@bubblegumshoestringracing1498]

I've seen that snake oil work on a lift

[@frankyalvarezhg3253]

What trans and drive shaft are you running?

[@SPPTVarmy]

4l80e with a custom made driveshaft

[@georgem.6136]

Try Rotella 15-40 Diesel oil, has solved many lifter related noise issues

[@SPPTVarmy]

Just bought some actually.

[@honestmechanic7974]

Don't think your gas prices are bad. Try living in Vancouver. Regular finally started coming down. Was in $1.60's/litre

[@owenarsenault5955]

I know, I laughed at his $1.40/L . Them flat lander's dont know how nice they have it east of the rocky's

[@hotrod_kris9395]

Can I just buy a new pin? Great video by the way!

[@SPPTVarmy]

Yes they sell new pins.

Hey rob I have a turbo 350 behind a cammed n springed ls1 with a stage 3 shift kit and a b n m pro ratchet shifter I plan on going for the billet 78/75 or gt 45 n turbo it using existing cam n springs I'm after 500 at the tyres with room to up to 700 will the turbo 350 be up to it if so what will I upgrade in it

[@joshkicklighter9513]

I have a 4l80e I’m rebuilding put all new pushing in having a issue where the pump slides down into the bushing is it supposed to be difficult noticed it will not rotate at all in the bushing has anyone else come across this issue

[@SPPTVarmy]

They are pretty tight, at least mine was. If it wont rotate at all then something isnt seated right.

[@donaldonleyjr.1582]

Did the same to my 4l80e in a plow truck few years back. Had it in and out 4 or 5 times to get length right. Worked good...then sold it before the next winter so dont know how long it lasted.
