5R55N 5R55S 5R55W Transmission Overhaul Master Kit With Steel & Friction Plates Fit Ford Lincoln Mercury Jaguar 5 Speed AT Gearbox

This full master rebuild kit is exclusively matched for Ford 5-speed automatic transmission models 5R55N, 5R55S, 5R55W, compatible with Ford, Lincoln, Mercury and Jaguar vehicles equipped with this series gearbox.

The kit integrates all core overhaul accessories required for full gearbox disassembly, including complete friction clutch plates, matching steel separator plates, full housing gaskets, shaft oil seals, O-rings and hydraulic sealing washers. It solves common AT failures such as slipping during acceleration, harsh shifting, transmission fluid leakage and delayed gear engagement caused by worn friction discs and aging rubber seals, a one-stop overhaul solution for professional repair shops.

Warm Reminder: The three derivative transmission codes share this unified overhaul kit. If you cannot confirm vehicle fitment, send complete VIN code to our sales team for free matching verification before bulk orders to avoid mismatched kits.

1. Complete set of friction clutch plates with high friction coefficient lining
2. Matching heat-treated steel separator reaction plates
3. All gearbox housing composite gaskets & paper sealing mats
4. Input/output shaft oil seals, pulley side shaft seals
5. Valve body hydraulic O-rings and small anti-leak washers
6. Torque converter sealing gaskets and dust-proof tiny seals

High Friction Coefficient Friction Plates

Friction discs adopt premium paper lining with stable friction performance, anti-burnout, resistant to high temperature and long-term heavy load, no slipping after overhaul.

Hardened Anti-Wear Steel Plates

Steel plates undergo high-temperature quenching treatment, flat and wear-resistant, effectively extend the service life of the whole transmission assembly.

Full OEM Precision Matching

All plates, gaskets and seals are manufactured strictly per OEM drawing dimensions, direct plug-and-play without cutting or modification.

All-In-One Complete Overhaul Set

No missing tiny sealing accessories, repair shops do not need to purchase separate friction discs, steel plates or gaskets separately, greatly improving overhaul efficiency.

Wholesale Friendly Cooperation Terms

MOQ only 1 set for sample trial, in-stock goods shipped within 3-5 working days, tiered favorable price for large bulk orders, stable continuous supply for long-term global dealers.

1. Raw Material Inspection: Test friction coefficient, heat resistance of friction lining and hardness of steel plates;
2. Precision Stamping & Molding: CNC molds ensure uniform size for each gasket, seal and friction disc;
3. Visual Full Sorting: Eliminate warped steel plates, cracked gaskets and deformed rubber seals one by one;
4. Complete Kit Matching Check: Manually count all parts to guarantee zero missing accessories in each kit;
5. Dust-Proof Independent Packing: Each kit packed in sealed plastic bag with outer export carton for long-distance sea transportation.

1. Installation requires professional 5-speed AT transmission repair technicians with dedicated disassembly tools;
2. Thoroughly clean gearbox housing, valve body and internal metal debris before assembling new parts;
3. Soak all new friction plates in qualified AT fluid for at least 15 minutes before installation to avoid dry burning;
4. Coat thin layer of transmission fluid on oil seal lips to prevent scratch damage during shaft assembly;
5. Complete full gearbox assembly, clear fault codes and conduct road test to check shifting smoothness and zero leakage.

Q1: Is there an extra charge for reinforced fumigation-free wooden case packaging?

A1: Small orders with less than 20 sets will have extra fees for fumigation-free wooden boxes. If your bulk order quantity reaches our standard threshold, we can upgrade to reinforced wooden packing free of charge. We will list all packaging costs clearly on the quotation sheet in advance, without hidden charges. The thickened wooden frame can protect friction plates and steel plates from deformation during long ocean shipping.

Q2: Can you remove redundant gaskets to make a simplified half kit only with friction and steel plates as repair shops require?

A2: Absolutely, we support customized simplified half kits that only keep friction discs and steel separator plates, cutting extra unneeded gaskets, oil seals and O-rings as your repair shops demand. We will confirm the exact parts list with you before production. This lightweight half kit reduces packing volume and procurement cost for your customers, and we offer stable tiered prices for customized bulk orders.

Q3: If I place a combined order with transmission oil seals, valve bodies and differential parts together, can I get a lower combined wholesale unit price?

A3: Definitely, mixed bulk orders combining this 5R55 overhaul kit with our oil seals, valve bodies and differential spare parts qualify for extra bundled discount. We will recalculate a more favorable unified unit price for all items on your quotation. This mixed purchasing plan helps you cut total procurement cost and consolidate one shipment to save separate ocean freight fees.
