I'll list what it done here to a TH400 during correct preparation for high performance use. Full set of bushings, thrustwashers, steels, frictions, low sprag, int sprag (34 element and early drum if needed), seals, gaskets, shift kit, both bands (hd), governor gear, new modulator and a filter. Short apply pistons are added to both drums for maximum friction capacity. Just a ballpark figure for parts is about $450, more or less depending on the year of the transmission and the type of direct drum used. The later units are more expensive as they use the roller clutch in lieu of the sprag type and must be replaced. Planetaries are also closely inspected and replaced as needed. Final cost for a correctly prepared unit will be $550 to about $700. I'm constantly price shopped and have heard at least 1000 times that they can get them "rebuilt" elsewhere for $250 dollars (or less)......Cliff

So Cliff, I’ve asked SEVERAL Facebook groups now without any luck at all!! So I’m your opinion, what would be the best trans filter I can use for my 75 Formula with a little upgraded Th400. Keep in mind, it has an 8.5” 10 bolt with 4.56 gears and the car is driven to and from the dragstrip (roughly 1-1.5) hour drive one way. So needless to say, Dad used to stop the car 2 to 3 times to cool that th400 off before getting to the strip. Plan here soon is replace the 4.56’s with 3.42’s and also add and transmission cooler in front of the radiator. I remember when the old man Jim Butler was still running Butler Performance in Leoma Tennessee and he had suggested to Dad to actually run 3.42’s from the get go, Dad was just wanting absolutely everything he could get out of it. Well now that I’m building a new stronger motor, I’m hoping the 3.42’s with a 28” tall tire will go through the finish line almost wound tight in 2nd gear and still have high left to cruise home. So Cliff, what filter would you recommend for my th400 that’s in the car now?
