RE4F03A Shift Kit Installation

Front Drive Nissan--Without TV Cable

Vehicle Applications

• Sentra GXE 93-99
• 200SX 95-98
• G20 Infinity 94-99

Kit Benefits

This kit is designed to provide improved shifting performance, addressing issues such as rough 2nd gear shifts (especially when cold), lack of 3rd gear after a 3-2 or 4-2 kickdown, direct clutch inner seal leaks, and improving 1-2 shifts, 2-3 shifts at heavy throttle, and 4th gear/lockup engagement.

Upper Valve Body Procedures

General Description

Enhances the 1-2 shift for a shorter, smoother engagement with no bangs.

Checkball Information

Use five steel checkballs, sizes .214 to .218. Do not use plastic balls. Apply Vaseline to keep checkballs in place; do not use grease.

Installation Steps

Hello Mechanic: Install the accumulator valve first. Then install the flat washer on the stem of the accumulator valve, followed by the remaining parts as shown.

Step 1: Accum Valve Removal

Remove the accumulator valve. Chamfer the partition as shown at the bottom of the page. Clean the bore. Reinstall the valve, the WHITE spring, end plug, and retainer.

Diagram description: A valve body is shown with checkball locations marked with 'C'. Illustrations depict a 'Stem', 'Accum valve', 'WHITE' spring, 'Retainer', 'End plug', and 'Piston'.

Here's Why:

The edge of the valve (A) contacts the partition (C), deforming the bore and causing the valve to stick at land B.

Here's how to fix it:

By hand, create a slight chamfer in the valve bore at point "C" using a sharp 7/16" or 15/32" drill.

Image description: A drill bit is shown with the text 'Turn 7/16" or 15/32" drill by hand in bore.'

Step 2: 2nd Accum Piston Installation

Install the washer and the PLAIN spring provided with the kit.

Illustration description: Shows a 'Washer', 'Plain' spring, 'Retainer', 'Piston', and 'End plug'.

Step 3: Pilot Valve Installation

Install the YELLOW spring.

Illustration description: Shows a 'Pilot Valve' with a 'YELLOW' spring.

Upper Separator Plate Procedures

Instructions

Upper Valve Body: Enlarge a specific hole with a .110 drill.

Upper Separator Plate: Enlarge specific holes with a .086 drill.

Diagram description: An image of the Upper Valve Body shows an arrow pointing to a hole labeled 'Enlarge this hole with .110 drill.' A diagram of the Upper Separator Plate displays multiple holes. Arrows indicate specific holes to be enlarged with drill bits. Drill bit sizes shown are .046, .086, and .110.

Channel Casting

Checkball Information

Use six steel checkballs, sizes .214 to .218. Do not use plastic balls. Apply Vaseline to keep checkballs in place; do not use grease.

Image description: Two images of the Channel Casting are presented, revealing intricate internal passages. Checkball locations are marked with 'C'. A 'Filter screen' is indicated.

Main Separator Plate Procedures

Instructions

Enlarge holes with a .110 drill.

Enlarge a hole with a .086 drill.

Enlarge a hole with a .046 drill.

Diagram description: A diagram of the Main Separator Plate shows numerous holes. Arrows indicate specific holes to be enlarged with drill bits of sizes .110, .086, and .046.

Main Valve Body Procedures

Step 1

Install the ORANGE spring.

Step 2

Install the GREEN pressure regulator spring furnished.

Step 3

Enlarge the limit drain holes with a 1/4" drill.

Step 4

Install Springs & Gold Steel Balls furnished. Gold Steel balls are .265 diam.

LISTEN UP:

Install the retainers in the correct locations in the Valve Body (VB).

Image description: An image of the Main Valve Body is shown with callouts for installation steps. Labels include 'Retainers', 'Dummy valve', and 'End plug'.

3-4 Clutch Drum and Band Adjustment

Band Adjustment Check

You must be able to wiggle the band back and forth at least 1/16".

Band Adjustment Procedure

Snug the band with a short wrench, then back off 2 to 2-1/2 turns and tighten the lock nut. Use a 14mm wrench and a T30 TORX bit.

Installation Steps

Install the 2nd piston with the new cushion seat and spring. If the band wiggles on the drum 1/16" by hand, the band adjustment can be skipped.

Install the Cushion Seat, ORANGE, and RED springs furnished.

Insert the overlap part of the Wire into the groove at 6 O'clock. Then shape the Seal as shown and install it into the groove.

Technical Note

A poor design in the 3-4 clutch inner piston seal can cause the transmission to lose 3rd and 4th gears, which is usually worse when the transmission is hot or after kickdown.

Illustration description: Illustrations show the 4th piston, 2nd piston, cushion seat, RED spring, ORANGE spring, and a removed hard washer. Also depicted are the 3-4 Clutch Drum and 3-4 Piston. Diagrams illustrate 'WIRE' and 'SEAL'. An image of the transmission case shows a circled area for band adjustment.
