Hope someone has a little advice to give i'm using the sonnax 2nd and 4th servo kits. Does that seem odd? I did find it odd also that my pin and the 2nd gear piston have a little play between spring and washer e-clip? Someone had said i have a worn out spring there I just used the oem spring and on the oem setup it was against all the parts. But i never had to grind/file on my tip of my pin at all. I unfortunately had to pull the 4th back out due to my 2nd not pushing in all the way for some odd reason. I just dont have enough room to get anything in there I used a tape measure and figured i needed more than a 1/16th and no more than 1/8th it all looked good with no o-rings had a heck of a time trying to get it together with the o-rings on and now there is like hardly any play at all in the servo and the retaining ring. I was wondering if anyone actually got a dial indicator and checked the pin travel while the tranny was in the vehicle. Is there a chance that the pin being stuck in its bore caused the newly rebuilt transmission to fail like I believe?Ģ.I dont know if it has been address before, it might have and i'm not finding it but. I have lurked around the web for a few weeks and haven't found any threads mentioning this particular problem, and I could use some advice before I cough up money for a new apply pin.ġ. I cleaned off the pin and it appears to be undamaged with no wear or markings.

Then the forth gear servo with snap ring. Assemble all components without seals - This means install the second gear super hold piston, with the sonnax extra long pin, springs, and washers. I eventually got it out, but it doesn't move freely in its bore and has a tendency to get stuck. old yukon said: After checking up again with Sonnax I got the following. The real problem was the apply pin being stuck in its bore. I ended up removing the E clip and taking off the pistons one at a time. The cover came off pretty easily after a few whacks of a hammer, but the pistons themselves wouldn't budge. The only odd thing that I encountered was the 2-4 servo assembly. The molded pistons looked fine, and all the other frictions were brand new (I could still read the borg warner label on them). 3-4 clutch pack was burnt up like expected, but everything else looked good. I dropped the transmission and took it apart. The problem was no shift into 3rd or 4th gear. He didn't want to put any money into it anymore so I picked it up for a pretty good price. I bought it back in July because the owner just paid for a transmission rebuild and during his test drive it went out again.
