Not counting the deep pan and remote filter, everything else on my list ran about $ 250 total. Two sonnax bore plugs are about $ 15. Doing the aluminum accum pistons and/or pinless ones is under $ 20. It's designed to reduce plug wear and better maintain the hydraulic circuit.Īt a minimum, I'd add the Servo Check Valve to your list, it's only about $ 10.
The Forward/Reverse Bore Plug is an upgrade to the OE version. 310 pin for 82' (?) and above, but the 94' and above is a. The aluminum type is an upgrade to the plastic.
The OE accum pistons for 98' and above are plastic (it says right in the manual that GM was trying to save money). In the 1-2 accum, the Transgo kit changes the spring setup in such a way that the pinless type won't work. The Transgo replacement spring for the 3-4 accum will work with the pinless piston. They are vastly better in design and durability than the OE type. Sonnax pinless accum kits can be used in the forward and 3-4 bodies. The other pieces in the list are kind of optional. It goes into the case right behind the servo check ball capsule. Guys who have tried say it works as advertised. It improves 2-3/3-2 shifts/downshifts and helps extend 3-4 clutch life. The Sonnax Servo Release Check Valve is a nice piece. Just doing these will yield a big improvement.Ī Transgo plate is a nice upgrade in quality, plus like you said you're already in there. The Transgo HD-2, Corvette Servo and OD Super Servo are like the base upgrade. On the street I just like getting up to the speed limit really fast My goal was to do the maximum possible w/o taking the trans apart. My main goal I guess is "sporty" shifting and better control, but not too extreme. Seriously, I do some medium towing and will eventually do some limited 1/4 mile runs. GM Hey GM, been real busy the last few days, but finally got some time to follow up on this.īasically, I'm building my trans to handle my lead foot Oh yeah, I allready have a big B&M cooler. What about the other parts? ie, the 3-4 accumulator piston kit, the servo release check valve, and the servo release check valve?
Since I would already be in there, would I want to install the hardened seperator plate? Are you building a transmission for race or towing?ġ x Superior Super Servo Piston Kit, 4th apply OK SALMMADINGDONG, I see your parts list. If you've already worked with the 700R4 VB, stepping up to a 4L60E will be cake for you. The 4th apply Superior Super Servo will help with 4th gear holding capacity and 4-3 release.
You may have noticed by now Nelson Performance can really help you out in this area. Just as GMCwantsLS1 said, a TG kit would require a PCM tune. The HD-2 is the same thing, sans the video.
If you get a Transgo shift kit, you can go with the PSK, which includes a pretty decent instructional video. There is the "GM ATSG Techtran Manual" and "Update Manual". Here's a post from today that includes the parts list I'm using:Īnother thing that helped me out ALOT are the ATSG 4L60E manuals. Plus, there are plenty of other guys here, that are much more knowledgeable than me, who can help you. A temp guage would be a good thing to have also. Also get some tuning so you can make good use of the improved shifts you will have. JMO but I would get both servos, HD shift kit and the biggest tranny cooler you can fit.
