kinda funny
the tranny case is the same as in the corvette, and the corvette servo is a stock part in that tranny.
must be an issue with the instalation
Totally agree. If it was a problem, GM wouldn't have used this part in the vette's 700r4/4l60 trans stock from the factory. I've installed many of the larger servos in plenty of 700r4/4l60 transmissions w/o any probs. If it is installed correctly, you won't have any problems.

<------- two years, no issues.
Just like KrautBurner said, if the Corvette servo was a problem then a ton of Corvettes would be running around with cracked transmission cases. However, that is not the case and the servo itself is not the issue.
If you install it correctly then there is no reason the case would get damaged from the Corvette servo.

Ive had mine sitting in the tool box still brand new that i bought for my two door and now was going to get around to installing in my current tahoe myself. I do all maintenance and repairs myself but after reading this ill have a trans shop do the install so I wont be wondering if all is seated correct. Figure it couldnt cost much labor to do this

yup i had the same thing happen to me...its not that the trans is weak in that spot, its that the snap ring doesnt get seated correctly. I did mine and made it half mile down the road until it shot out, and fluid was everywhere..I got lucky and it didnt break the case..turns out i didnt have the snap ring on totally..live and learn i suppose..i ended up blowing up my trans since i burnt up some clutches when i lost my fluid

Im not saying its a bad part. I ran one in my 700R4 for years with no problems. I did have problems putting the ring back in for the 4L60E (yes i installed it myself). But i pulled the servo back out and reinserted and the cap and ring went in perfectly (or so i thought). Its funny that it took 3 months to finally crack the case. I didnt get to take any pics of the old case to show you guys where it exactly cracked at. But when it was still in the vehicle it looked like the bottom of the servo portion of the case just exploded. Im not saying the servo is a bad part because i do have friends that are currently running it. But like me another friend of mine busted his case as well. So just beware is all im stating. Best to get a tranny shop to install so at least they may warranty it if it busted in the future.
Got a question involving the servo. Did any of you guys notice when taking off in 1st sometimes it feels kind of sluggish. ALmost like a slipping. Then when driving and punch the gas a little, it jerks a little into 2nd gear. Is that normal for the servo? Otherwise i notice no problems. Just wondering if this is just my imagination or suppose to be like this.
