Updates to the Transmission

  • Updated Overdrive & Intermediate Servo Bore Sleeves
    Updated Overdrive & Intermediate Servo Bore Sleeves, which requires special reaming tools, that re-bores worn out aluminum servo bores Severe wear of the case at the servo apply pin bore due to continuous pin oscillation can result in burned clutches, shift complaints, and destroyed cases. This bore wear is an extremely common issue as early as 50k miles! This problem is the most overlooked issue by other builders. The sleeve is made from highly wear-resistant bronze alloy, and allows the case to be refurbished to provide proper clearance with the servo apply pins.
  • Updated Superior K0105 Front Ring Gear Hub Snap Ring
    Superior Super Tuff Heavy Duty Snap Ring, which helps prevent common failure of the planetary gear sets and forward clutch drum, which is a very common issue with the OEM (FORD) Snap Ring.
  • Updated Superior Shift Correction Kit
    Due to the factory design of no cooler flow cold, it is extremely temperamental to fill and get a correct level, as well as running extremely hot compared to others without flow control systems. Superior finally broke thru with a patent pending Sure-Cool Full Time Cooler Flow Valve along with enhanced Lube system that nearly triples the Flow thru the cooler and parts, especially the O.D. Planetary. These Flow Control Upgrades virtually eliminate front Planetary Burn-up due to lack of Poor/ No lube. This new system also furnishes a built in cooler bypass system that if the unit is extremely cold (fluid starts to gel) or in the event the cooler is blocked / restricted, flow to the parts still occurs – protecting your transmission investment. Also includes Updated “No Stick” Line Pressure Relief Valve Kit. Updated Lock-up upgrade system that allows an On-Off Type Apply. Updated 3-4 Drum Piston return springs replace the often found fatigued originals. Kit also addresses several TCC error & shift solenoid error codes as well as P0740. Keeps Solenoid Blocks, Parts and Components Cooler and lubricated with these new system Upgrades.

The owner was very involved with my 4l80e swap. Had an internal harness connector o-ring leak they helped me resolve to prevent fluid from leaching up into the main input harness. After that the trans performed flawlessly. Great communications and shipping crate professionally done. I will use them again I am sure. I would proudly wear a shirt or hat with their logo. Thanks team.

Needed a transmission for my dodge 5500. They shipped it quickly to my mechanic then let me bring the core in since I was going to be in the area, so I didn’t have to spend a bunch on shipping to get my core deposit back! Molly is the best to deal with! Can’t go wrong with them!
