She's a high mileage ol girl like mine. I have about 20k on you though. I did just have to replace the head gaskets so I chose to pull the engine and replace piston rings and main bearings and rear main seal. It woke my truck up a lot. Mine is 100% stock btw. 👍🇺🇲
Just recently put a corvette servo and external cooler on a fresh rebuild w my 4l60e. Haven’t driven it yet but now I am excited about making the call to do the servo
Fresh transmission fluid, and a fresh transmission fluid filter is always a good idea if it has been a long time since it has been done. Never have it flushed though.
I got a 2001 blazer 4.3 with the 4l60e and 4wd been rebuilt 3 times bc nobody ever kept it maintained there decent transmissions and not that bad if you change trans fluid and filter and I plan on doing the corvette servo in mine as well but right now I don’t have the funds to do so but maybe later I plan on it but it’s Ab time to change my fluid and filter on mine
Yup, you need to keep up with maintenance for sure and most people don’t. Have you looked at the price of the Corvette servo? It is actually pretty cheap.
Thanks. No, it is all stock. I believe that it was changed out by a previous owner because I doubt the original would look and perform this good 17 years and 214k miles later.
@@whiplashtv2022 my 01 c1500 I just got has all updated interior lights, pretty common when the clusters need stepper motors replaced to update lights
Don't replace it. Pull the display out. Open it up and you will find 4-5 surface mount resistors lose from the board. As they heat up they flex and break the solder. Just solder them back on and you're good. Took me 10 minutes to solder mine back. Took longer to remove the cluster.
Would it be worth it to install the corvette servo into a daily driver? I've got a 2000 Chevy Astro AWD (4.3l) with 150,000 on it that needs a rebuild.
Hi, fellow Texan here: west Houston. My local installer keeps telling me the 4L60E has a rpm limit of 5500. Does this servo hold the shifts beyond that limit? For the rebuild on my 1998 C1500 5.7 daily driver, I got the one step down from the Sonnax Corvette servo .74 ratio, which is part number 77701-02K at .63. From what I know, the .63 is what GM used in the 4L70E. I have about 22 other Sonnax upgraded parts on hand for this, so do you have any words of wisdom from this swap you could share? Thanks and excellent video.
@jaywestfall3439 thanks for watching. I have never heard of the 4l60 transmission having a 5,500rpm limit. I had this truck shifting at 6,000rpm at wot with this servo. If it was cammed, then that shift point would be even higher.
@whiplashtv2022 Oh, man. You just reminded me. We swapped out the stock roller cam for the Chevrolet Performance roller cam 14097395. It's the one used in the 383 crate engine.
Hello, thank you for your video. I'm struggling with that servo install. Any suggestions on how to hold pressure against the servo case while trying to install the rigid C clip?
I HAVE A VIDEO HERE ON THE CHANNEL OF THE INSTALLATION! Push in on the center of it with something while inserting the snap ring. Get a buddy to help you if you need an extra set of hand, or use something long enough to apply press with your leg and free up both hands.
I have a 96 GMC Sierra with 4l60e I just had my transmission rebuilt at 544, miles. When I got my truck back 2nd gear was slamming. Took the truck back and they put the Corvette Servo in. 2nd gear cleaned up but 3rd gear is taking too long to go into gear when getting on the highway, getting up speed after leaving a red light. Transmission guy says nothing is wrong with it. My heart just sank. Any suggestions?
I agree. However he says people pay good money to have it shift like it is. I said I don't want or like it shifting like it is. I was told by a mutual friend of the mechanic dog the piss out of it burn it up! Make him do it right
I'm looking at this mod paired with Transgo shift kit and some fresh solenoids. Do you have any experience or recommendations with the kit? My tranny gets stuck in 3rd or 4th every now and then. Usualy only on a hot day and when idling alot. I can usualy manually shift down into first but it hangs then slams a bit. 333k on the truck, trans had probably never been serviced. Im not a pro but ive read this is just a servo issue. I figure while im in there, I may as well do the kit and the servo
Definitely do the Corvette servo (link is in the video description). TransGo HD2 is a good shift kit but don’t go with the harshest shift settings. It is a good idea to change the transmission fluid and filter but DO NOT FLUSH it.
I got a 1996 K1500 6in lift with "36 tires and 16" rims its a beauty but even when in 4H itll stuggle to go over shit unless you pin that 350 to around 1800-2000RPM it feels a little like it doest got enough umph for those tires atleast with 3.73 gears but the corvette survo might help with better apply pressure but in all honesty i think it just needs a modest 383 😂 then the sob will pull like a damn elephant 🐘

@@jwren007 .01 better has you believing that you need to keep your stock servo because it was 1 hundreth better in the 1/4 mile? Lol Do you not understand that they are even, and not one worse than the other? Do you not understand the purpose of the Corvette Servo? Your transmission is much much better off and will last longer with a Corvette servo because your stock servo doesn’t apply enough pressure to the clutches and causes additional wear and slip compared to the Corvette servo.
@@robpaul7900 no, I don’t stay in 1st and 2nd most of the time. When I am accelerating harder than usual then it can take up to 55mph for it to shift out of 2nd. Normal driving will have me in 4th gear before 55mph even comes.

How is it ? Just did the same waiting to get my truck back. Just Got a 40k trans cooler a full rebuild and a corvette servo put in. Can’t WAIT
It should run good.

Yup, you need to keep up with maintenance for sure and most people don’t. Have you looked at the price of the Corvette servo? It is actually pretty cheap.
Does the Corvette servo affect the transmission by reducing its lifespan?
No, it lengthens the lifespan due to less transmission slip.
I’m considering this mod too along with the corvette convertor. Not looking to be faster, just want to prolong the transmissions life
The different converter isn’t going to do anything to prolong the lift of the transmission but the servo definitely will.

@@ericcastillo309 you’re welcome, thanks
Should work well paired with a trailblazer 2600 stall converter
Yes it will work well with a stall. If/when I put a stall converter in this truck, it won’t be smaller than a 3200-3600.
Is your dash modified? The gauges and needles are much better (brighter) than mine
It is all stock. It is common that they go out and dim with age. You might need a new one.

Tow/ haul mode and in 3rd gear I run low to mid 14s constantly with an extended cab I also have shorty headers and cold air intake
What gearing does your truck have?
What elevation are you at? What mods?
I’m betting that he has better than 3.23 gearing.
Does tow haul mode give you extra hp??
Lol, no it doesn’t. Tow Haul makes changes to how it shifts. That is it.
