The Rebuilding Process

Experience the Suncoast 10L1000 transmission rebuild process—a blend of precision and practicality that elevates reliability to new heights. We start by disassembling the transmission, removing all worn "soft parts" to make room for a fresh start.

Our specialized hot wash tank, heated to 198 degrees, becomes the gateway to cleanliness as casing and housings undergo thorough cleansing. This step ensures a pristine foundation for the transmission's revival.

As the components emerge, they face scrutiny from our skilled technicians. Hard parts undergo meticulous inspection, with any signs of wear or damage identified and addressed. Only those fit for duty proceed to the next phase.

The casing receives special attention, with every nook and cranny inspected for flaws or fractures. This critical step ensures structural integrity, safeguarding against future issues.

What emerges from this process is not just a transmission, but a testament to reliability and performance. With the Suncoast 10L1000, you're not just getting a product—you're investing in peace of mind and dependability for the road ahead.

  • Steels engage on 4140 steel dowels, instead of the problematic cast aluminum drum assembly

SunCoast's Category 2 transmission also comes with our 10L1000 High capacity "E" clutch drum with billet apply piston. This new High Capacity 10L1000 clutch drum arrives fully assembled for effortless installation. Our high-capacity 10L1000 "E" clutch drum addresses all of the facets affecting the durability of these clutches in highly demanding driving situations. 

To improve clutch life we first started by simply increasing the clutch count. This new 10L1000 clutch drum boasts an astounding 29% increase in clutch capacity compared to the factory drum, surpassing any other aftermarket option on the market today by an additional 15%.

Another key point we address here is the deflection in the E-clutch. This is especially exacerbated when operating under higher line pressures, often experienced during heavy-duty or higher-load situations.

The new SunCoast 10L1000 “patent-pending” E-piston is engineered to eliminate any possibility of apply-deflection or coning. By using superior materials and increasing the apply piston diameter, we have significantly expanded the contact surface area. Crafted from billet T6061 aluminum bar stock and meticulously CNC machined in-house to exact tolerances, this new “E” Drum Apply Piston for the 10L1000 embodies SunCoast's excellence in design.

Moreover, we've tackled the issue of rapid drum degradation caused by steel tooth chatter/engagement. SunCoast's solution involves the designing of specialty 4140 steel dowels for the steels to engage with, replacing the highly malleable factory-cast aluminum. This design allows us to ensure reliability while keeping reciprocating mass at a minimum.

The friction material was also addressed as we have changed from the factory friction material which is engineered and designed to provide maximum "NVH" for comfort. This new 10L1000 drum is equipped with Raybestos GPZ clutches.

The "F" Clutch

This clutch is also prone to premature wear as we have seen with other Lepelletier Ravigneaux Gear sets...oncoming clutches in higher gears seems to take the blunt of the beating. With the new 10L1000 transmission, the "F" clutch is no exception.

The "F" clutch is engaged in R,4,5,6,7,8 and 9th. The quickest path to early or premature degradation to this clutch pack is wide open throttle or heavy-load-indexed 3rd to 4th shifts. This is especially prominent in applications where torque management has been deleted.

Suncoast has corrected this issue by adding 25% more capacity to this clutch pack by taking it from 4 clutches to 5 in this particular clutch pack.

The "D" Clutch

It is not uncommon to see rapid degradation along with premature failure with this clutch pack in even stock form. 

The "D" clutch is engaged in P, R,1,2,3,4,6,7,8,10. Where the problem lies is in its oncoming clutch responsibilities when engaged in 6th gear as the oncoming clutch. With this responsibility in higher horsepower or more demanding driving situations it becomes very obvious uptown teardown this clutch has seen its share of abuse.

Suncoast provides GPZ friction material, providing higher friction coefficients, increasing torque capacity well beyond the factory limits. This along with our higher apply pressure with our high volume 10R140 transmission pump creates the perfect environment for more reliable shits. The new Suncoast 10L1000 transmission clutch module requires absolutely no machining or modifications to your current unit...we supply everything needed.

The Pro Loc Valve Body and Pump

With the SunCoast 10L1000 Pro Loc valve body, we are addressing several key issues we have seen in regard to the 10L1000 transmissions. This is not an approach that is simply bumping in more line pressure in hopes of ascertaining more clamping force; it’s a multi-faceted approach addressing several key issues when exposing these units to more demanding driving environments. These range from heavy towing and hauling to street racing and drag racing. 

The factory 10L1000 transmission lock-up circuit is an impressive one, in that it can make converter lockup seem somewhat uneventful. The refinement in its engagement is definitely next-level to what we have seen in the past. As nice as this feels in reference to the NVH (Noise Vibration Harshness), when we start introducing situations where the load demands are testing the limits or outside what the vehicle was initially designed for, it can become a huge problem. 

In our SunCoast 10L1000 Pro Loc Valve Body we are specifically looking to decrease the time from initial lock-up apply to zero turbine slip. In doing this, we are changing the lockup circuit by replacing the torque converter clutch (TCC) valve in order to increase lockup holding apply fluid pressure. The lockup oil transition time is also improved by modifying critical oiling circuits for the fluid to reach the TCC clutch, resulting in quicker apply time, and therefore, reducing TCC clutch degradation. By reducing degradation per apply cycle, we are allowing for improved reliability and performance.

(NOTE: For maximum results in power levels exceeding 800HP, it is highly recommended that the TCC apply offset be changed in the factory file calibration)

The next facet we address is the lube circuit. The lube circuit on the 10L1000 transmission is responsible for supplying oil to the planets, clutches, bushings, etc. From the factory, the lube circuit oil is dispersed throughout the transmission as low as 6 PSI. Under normal load demands, this is perfectly acceptable. In more stressful and demanding situations, an increase in lubrication to clutches, steels, planets is ideal for removing heat and dealing with the increased demands. 

In our 10R140 Valve Body we are specifically addressing this circuit from 6 PSI to a whopping 20 PSI. This is a 250% improvement from the factory calibration, resulting in reduced frictional heat generated. This reduction in heat helps lessen pre-mature failure that can become increasingly evident in high horsepower applications.

Another modification to our SunCoast Pro Loc 10L1000 Valve Body involves the regulator valve (latch valve) circuit. This oil circuit is responsible for fully engaging the clutches, allowing for full clutch line pressure. In factory form, the regulator valve we are specifically targeting is responsible for A, B, C, and F clutch packs. Of course, our primary clutch pack concern is the 'F" clutch, which tends to be the first and most prominent clutch pack failure with the 10L1000 in higher horsepower or more demanding environments.

In a factory 10L1000 valve body calibration, the regulator valve (latch valve) becomes fully engaged, allowing full fluid flow for engagement at 120 psi. When this occurs, the oncoming clutch pack has maximal clamping force. When the clamping force is engaged to max capacity, we ascertain the greatest static and dynamic holding capacity. In stock form or even mildly modified vehicles, this is perfectly suitable; however, when we expose the vehicle to a more demanding environment this can be a weak link.

With our SunCoast 10L1000 Valve Body we are decreasing the required pressure to fully engage the regulator to only 80psi. This is a 33% decrease in pressure needed to maximally engage the clutch regulator valve (latch valve) resulting in a quicker shift apply when engaging clutches A, B, C and F. This quicker engagement not only shortens shift times, but it also decreases the heat resonating in the clutch pack, preventing premature degradation and extending clutch life. To improve this shift calibration even more SunCoast is evacuating non-critical oil to increase apply rate.

The factory overall line pressure is modified on this new SunCoast pump/valve body combo. SunCoast is increasing overall main line pressure as much as 60psi. This additional line pressure not only increases maximal clamping force of the individual clutch packs but increases overall pump volume production. To reduce the potential for runaway pressure and the over-compression of clutch fibers, the SunCoast 10L1000 Valve Body does have a built-in bypass, dumping excessive pressure above 420psi.
