Problem with the 4th gear shift at 40kmph speed

check the joint where the shift linkage attaches to the shift shaft at the transmission....you either have a pin missing in the joint or missed the splines when making the connection at the shaft...........Make sure it is in neutral at the shaft and inside the car at the shifter before making the connection at the shaft.............

Which transmission does yours have 4T65-E or 4T80-E ?

DEFINITION: A large engine RPM increase is noted in fourth gear, Drive range, with little or no vehicle forward speed increase. First, second, and third gear operation are normal. Shifts into fourth gear are soft or do not occur. Fourth gear ratio is 0.705:1.

Automatic Transmission Fluid Level
Low fluid level

Transmission Main Line Pressure
Low transmission main line pressure

Oil Filter Assembly
• The oil filter assembly (100) is missing, plugged, or damaged.
• The oil filter seal assembly (101) is missing or is damaged.

Control Valve Body Assembly
• The 3-4 shift valve (362) or the 4-3 manual downshift valve (360) is stuck or binding.
• Debris is found in the passages of the control valve body (301) or of the control valve body spacer plate and gasket assembly (396)

Case Cover Assembly
Distortion or damage occurs at the manual valve (404) or at the case cover (401), causing PRN oil leak.

Driven Sprocket Support Assembly

• A missing or not seated fourth clutch spring retaining ring (601)

If the shift linkage is not binding on the outside of the transaxle, then something inside like a shift fork has broken. The transaxle will have to be removed for repair. Such is the way with 20 year old cars where old things break, bad luck for you. It will be an expensive repair. An alternative is a used 5 speed from a salvager. That and a new clutch could have you going again in short order.

Hi Have you replaced the clutch plate? I believe the plate is worn and needs to be replaced and the throw bearing as well. Good luck.

Clutch plate worn out or clutch adjutment is too tight.

The reason could be that the gear teeth have worn out &/or the chain & sprocket are worn out. Both of them depend on the condition of the clutch plates and the oil level in the gearbox.

This problem is common in all Enfield Bullet 350 cc unless maintained every 6 months or so since two levers operate the gears(up & down). The chain sprocket being the main culprit. I have observed this by seeing the Army uses only Bullets & my Dad being an Officer I got plenty opportunity in driving them....................................sodeep

I really have to lift up hard and fast to get it to go into 3rd. My neutral finder is hard to press as well. Any suggestions?I'm having trouble shifting from 2nd to 3rd as well and sometimes to 4th. It starts to happen after I've been riding for 10 mins or so. I found that it helps to get my foot way under it so that I'm shifting using the top arch of my foot but sometimes it doesn't matter what I do, it takes 3-4 tries to shift. I adjusted my clutch but had very little effect. I tightened my chain too. I tried searching shifting on the forum and found mostly left to right shift conversion and down-shifting threads.,,,

There is pretty much a false neutral between every gear on an Enfield. You need to ease the gear up or down and do it by feel more than a hard up or down movement
