A little about PerformaBuilt transmissions FYI

--------------------------------------------------------------------------------















These are just a few of the things used in the level 1 build

1-Shown 1st and 2nd pictures are the rear and front planets. The planet clearance is allowed by GM up to .025 we never use a planet with excess of .020 clearance.

2-Next shown is the new low/reverse clutch set. All frictions are replaced with new.
3-The 4th picture shown is the new low/reverse steel plates

4-The 5th picture shown is a device called a case saver. It replaces the stock anti clunk spring and more evenly distributes shock against the case lugs. This helps to prevent excessive lug wear in the case or breakage of the case or lugs.

5-The 6th picture shown are the forward frictions these are the borg warner type. They are only used in our level 1. They are and excellent clutch but we use something stronger in our levels 2 and 3.

6-The 7th picture shown is of the new forward clutch steels Notice on all steels the finish is not real slick rather its just a little rough, This is to allow some oil to remain trapped between the frictions and the steels for cooling.

7-8th picture is of the high energy frictions used in the 3-4 clutch in this level, We install 9 of them stock is six or seven depending on model years 7004r-4l65e. The levels 2 and 3 get a different clutch set.

8-The 9th picture is of new reverse input frictions again frictions are never reused in any of our units.

9-The 10th picture is of the red wide band we use it has porven itself and impressive peice and is used in both our levels 1 and 2

10-11th pic is of the new pump stator Its very important this peice be in good shape for those rebuilding transmissions thenselves there is a comonly missed problem with these. Always feel around carefully where the teflon rings from the input shaft ride inside this tube as any wear there or even small grooves will result in premature failure of one or more of the clutch sets in the input drum.

11-The Precision seal kit we use is shown in the 12th picture. All seals are replaced in every unit.

12-13 and 14 are two of the steel pistons we use in place of the aluminum pistons that come stock in many units. Very late units allready have these. They are replaced in every unit.

13-15 is a pictures of the pump vanes these are replaced in every unit along with many of the other parts in the pump. I didnt have pictures of.

14-Picture 16 is of a new corvette servo used in our level 1 (Stock in F bodies and GTOs) Our levels 2 and 3 use upgraded servos

15- This picture # 17 is a picture of the bushings and some of the accum servos we replace in every unit.

16-#18 is a picture of a Borg Warner dual cage input sprag standard on all our build levels

17-#19 is a picture of one of the new style wiring harnesses we use with late models. Theres a nice improvement done to the plug for the PCS eliminating loose conection problems associated with the previous design.

18-#20 is a picture os the beast sun shell the sungear installed. The beast is not used with the level-1 but is with the levels-2 and 3. The level 1 gets a new hardened late GM style sunshell which though not as strong as the beast it a nice peice. Didnt have a picture of it.


Anyway these are just a few of the things that go into our level one at lease things I have pictures of. All friction areas are allways replaced never reused. All seals and steel modled pistons and new. Along with many other things I have not gone into. The level 1 has surprised us several times as a number of people have bought it and then later exceeded the max rating we placed on it and the are still going strong. click here for website level 1
