Ford 4R100 Transmission 1999-2003Part #: PLSD-4R100-2X
Every Sun Coast 4R100 transmission is modified and built to exacting specifications. Each unit is dyno tested upon final assembly. The Sun Coast 4R100 Ford transmission specifications are:
Custom pressure regulator steel sleeve, boost valve and spring.
Full time converter feed and lube valve.
Custom accumulator springs and steel capacity valve.
Larger line modulator valve (quicker shifts).
Modified cooler by-pass for max cooler and lube flow.
Optional Tugger® equipped valve body doubles holding power of low/rev clutches in manual low.
Prevents downhill clutch burn up when using an exhaust brake or engine compression braking.
Short-crisp upshifts with “class”, performance and durability
Clutch Pack upgrades:

Over drive clutch count increased to 4 friction elements (allows towing in O/D)
Coast clutch increased to 4 friction elements ( a must for exhaust brakes)
Intermediate increased to 4 friction elements (stops 1-2 slide)
Forward increased to 6 friction elements
Direct increased to 7 friction elements
Front and Rear steel 6 pinion planet carriers.
Overdrive steel planet carrier.
Increased spline area on forward clutch cylinder.

360 degree center support contact.
45 element spring clutch.
Redesigned coast clutch drum doubles capacity and eliminates snap ring failure.
HD snap rings.
300m billet input shaft
Mag-Hytec cast aluminum pan with new fasteners. This pan increases fluid capacity by 7 quarts and gives the case rigid support to prevent flexing under Hi load conditions.
Upgrade Option for $390.00 includes:
The Extreme Tow Package features the ultimate high load calibration parts for the E4OD and 4R100 transmission. With the SCD dual load center support the load is now shared with a added bronze support bushing. This keeps the intermediate shaft from point loading the center support bearing. The TransGo Tugger kit doubles low and reverse clutch pressure in manual low for downhill hauling, high speed pull-in to 1st and the high demands of an exhaust brake. It has increased cooling/lubrication, improved converter feed and torque converter holding capacity. The cooler is also upgraded to 391 sq. in on the 4R100. This is more than double OEM cooler.
All Sun Coast Ford transmissions include a new 40,000# rated OTA cooler. Sun Coast transmissions are shipped in a heavy plastic container, insuring protected delivery and to facilitate core return.
