    Just to make I did this right, I'll post pics. Did you happen to look at my TCC valve (teflon one) with that metal clip they put in midway on the valve? Was that just to hold it in while they put the solenoid in?

    The rubber o-ring isn't shown on the first pic but I did install it





    Thanks Dave you helped a lot

    Yep that looks correct. The metal clip on the TCC valve is just to temporarily hold the valve in place for assemply purposes. They are there from the factory but never reuse them and are not required to be there.

    I'm installing my Z-pack in for 3rd tomorrow and it says not to install pressure plate, is that the same thing as a wave plate? The Z-pack doesn't mention anything about using the 3rd clutch wave plate. The z-pack has has two .055" thick steel plates that are in the bottom of the pack that I think replaces the wave plate.


    Also for my 2nd clutch pack, I bought 2 thicker Alto steel plates that I can use to tighten up 2nd (I'll probably only use 1). Do I just replace any one of the standard steel plates in the pack, or is it better to use it towards the top or bottom. I'm assuming it doesn't really matter as it is only a couple thousands bigger, but I'll leave that for the experts.

    I have my frictions soaking in my amsoil trans fluid right now for tomorrows assembly.

    I think I paid $10 qt, I had in store credit so I decided to splurge and use it since I didn't need anything else.

    The 2nd drum bushings were giving me big time issues. The 1 side when in no problems, but the 2nd bushing seemed to be slightly to big. I spent almost 45 minutes trying to get it in. I put the bushing in the freezer and took even the torch to heat up the drum slightly so it was almost to warm to handle by hand. The bushing kept wanting to go in crooked, and I eventually got it in. The bushing was marred in a spot, and it a slight wave as if the bushing was to big and thats was why it was giving me issues.





    I had to put one of my bushing drivers inside the bushing to prevent it from getting deformed. Then I took a big metal bushing driver and put it over the one pictured to actually get it to go in.



    My battle damage fighting with the bushing That bushing owned me.





    You think I should just wait until Monday and buy another set of bushings from transtar (unless they sell individually), or should I not even bother. IF your curious as to why the bushing is not as shiny as the other one, I assembled it onto the other piece and spun it to make sure it fit fine as well as not making any weird sounds when I spun it. I figure the bushing is some type of copper/tri metal composition that is softer than the steel that rubs against it. If there were any high spots or slight bumps in the bushing, they would get pushed down and shouldn't grind or fall apart. That is assumption, but what do I know.

    Transtec View on Scotchbrite


    Rubber Accumulator Seals
    The lathe (square) cut accumulator seals in this kit are TransTec’s aftermarket design seals. The
    dimensions are slightly different, and the material is more abrasion-resistant than the OEM seals. The
    design of these seals was improved because of occasional wear problems with the OEM seals. The
    transmissions most affected are the 4T60/E and AXOD, due in part to the design of these accumulators.
    The following steps should be taken on every overhaul to prevent premature seal wear:
    1) Always rinse the case to remove any soap film left from the parts washer. The soap acts as an
    abrasive that causes seal wear.
    2) Always resurface the accumulator bores with Scotch Brite®. A smooth bore has no place to hold
    oil for lubrication. Without lubrication, seals wear out prematurely. (Scotch Brite is available through
    parts stores, body shop suppliers, or tool distributors).
    3) Always check the accumulator piston-to-pin fit, especially on the aluminum pistons in the 4T60/E.
    Any wear here will cause the piston to wobble in the bore and wear out the seal.

    I myself am going thru this right now with just the valve body that needs replacement. I already bought an acdelco reman'd valve body,a new PCS,TCC PWM solenoid,2 shift solenoids,shift switch,spacer plate,and filter/gaskets. I am just waiting on the parts to come in by the end of this week to get it done. A local trans shop quoted me $350 if I wanted them to do this in a day. I might consider them to get the car back with only a day of downtime. I believe $350 is pretty reasonable since I bought all the parts totaling $211 shipped. This would be a total of $561 total which seems about right in the area of $500-$600 parts/labor to tear down to remove the valve body and reinstall. I will post back once I get all the parts in before deciding whose going to do the work. So it might just be before and after posts to comment on what difference I saw with the new parts. Wish me luck on getting it done.
