'''Manual shifter''' refers to the interior gear selector used in manual-transmission [[Pontiac Fiero]] models.

The manual shifter allows the driver to select gears by moving the shifter inside the passenger compartment. Because the Fiero transmission is mounted behind the passenger compartment, the shifter operates the transmission through shift cables rather than direct linkage.

== Overview ==

Manual-transmission Fieros use a floor-mounted shifter located in the center console area.

The shifter is connected to the manual transaxle by cables. Driver movement at the shifter is transferred through the cables to the transmission shift mechanism in the rear engine compartment.

Factory manual transmissions include:

* [[Muncie 4-speed]]
* [[Isuzu 5-speed]]
* [[Getrag 5-speed]]

Because the Fiero used different manual transmissions, shifter parts, cables, brackets, and adjustment details should not always be assumed to interchange.

== Location ==

{{Image wanted|Photo showing the Fiero manual shifter inside the center console, preferably with the shift surround removed to show the shifter mechanism and cable connections.}}

The manual shifter is located in the center console between the seats.

The upper portion of the shifter includes the shift lever and shift knob. The lower shifter mechanism is mounted under the console trim and connects to the shift cables.

== Function ==

The manual shifter allows the driver to select gears.

Basic operation:

# The driver moves the shift lever.
# The shifter mechanism moves the shift cables.
# The shift cables move the transmission linkage.
# The transmission selects the desired gear.

In a manual-transmission Fiero, the clutch pedal must be used during normal gear changes.

== Shift pattern ==

The shift pattern depends on the transmission installed.

A four-speed shift pattern generally indicates a [[Muncie 4-speed]].

A five-speed shift pattern indicates either an [[Isuzu 5-speed]] or a [[Getrag 5-speed]].

However, the shift pattern alone should not be used as final proof of the installed transmission. Fieros may have been modified, repaired, or transmission-swapped.

== Four-speed shifter ==

Four-speed manual Fieros used a shifter appropriate for the [[Muncie 4-speed]].

The four-speed shifter layout differs from the later five-speed layout. Parts should not be assumed to interchange without verification.

Related topic:

* [[Muncie 4-speed]]

== Five-speed shifter ==

Five-speed manual Fieros used shifter arrangements for the factory five-speed transmissions.

Factory five-speed transmissions include:

* [[Isuzu 5-speed]]
* [[Getrag 5-speed]]

Although both are five-speed transmissions, the Isuzu and Getrag are different units. Shifter, cable, bracket, and linkage details should be verified before parts are interchanged.

== Shifter cables ==

The manual shifter operates the transmission through shift cables.

Manual-transmission Fieros commonly use cables for shift and select movement. One movement generally controls fore-and-aft gear selection, while the other controls side-to-side gate selection.

Cable condition and adjustment are important. A shifter problem may actually be caused by a shift cable, cable bracket, or transmission-end linkage issue.

* [[Shift cable]]

== Common problems ==

Common manual shifter problems include:

* Loose or worn shifter feel
* Worn shifter bushings
* Worn cable ends
* Loose cable attachment
* Damaged cable clips
* Misadjusted cables
* Incorrect shifter for the installed transmission
* Incorrect cables for the installed transmission
* Binding shifter movement
* Console interference
* Previous-owner modification or repair
* Shift knob or lever damage

Shifter problems can be mistaken for clutch problems or internal transmission problems.

== Symptoms ==

Possible symptoms of manual shifter or shifter-related problems include:

* Shifter feels loose or vague
* Shifter feels stiff or binding
* Difficulty selecting one or more gears
* Cannot select reverse
* Cannot select fifth gear
* Cannot select first or second gear
* Shifter moves but transmission does not engage the expected gear
* Gear selection does not match the shift pattern
* Problem occurs even with the engine off
* Shifter contacts console trim
* Excessive play in the shift lever

Symptoms should be diagnosed together with the clutch system, shift cables, and transmission linkage.

== Diagnosis ==

Basic diagnostic checks include:

# Identify which transmission is installed.
# Check whether the car has a four-speed or five-speed shift pattern.
# Inspect the shifter mechanism under the console.
# Inspect shifter bushings and pivot points.
# Inspect cable attachment points at the shifter.
# Inspect cable ends and clips.
# Check for console or trim interference.
# Inspect shift cables at the transmission end.
# Check cable brackets.
# Verify cable adjustment.
# Check whether the transmission linkage moves fully.
# Check clutch release if the problem occurs mainly with the engine running.

If the shifter will not select certain gears even with the engine off, inspect the shifter, cables, brackets, and transmission linkage before assuming a clutch hydraulic problem.

== Relationship to clutch problems ==

Manual shifter problems and clutch problems can feel similar.

A clutch problem may cause grinding or resistance because the clutch does not fully disengage.

A shifter or cable problem may prevent the transmission from being fully selected, even if the clutch releases properly.

Useful clues include:

* If the car shifts normally with the engine off but not with the engine running, check clutch release first.
* If certain gears cannot be selected even with the engine off, check the shifter, cables, and linkage.
* If the shifter feels loose or vague, inspect the shifter mechanism and cable ends.
* If the shifter feels stiff or binding, inspect cables, routing, brackets, and transmission linkage.

== Relationship to transmission swaps ==

Transmission swaps can affect shifter and cable compatibility.

The [[Muncie 4-speed]], [[Isuzu 5-speed]], and [[Getrag 5-speed]] do not all use identical shifter, cable, and bracket arrangements.

When evaluating a swapped car, check:

* Installed transmission type
* Shifter type
* Shift cables
* Select cable
* Cable brackets
* Transmission linkage
* Cable routing
* Reverse-light switch wiring
* Full gear engagement

A transmission may physically bolt in but still have poor shifting if the shifter and cable system are mismatched.

* [[Engine swaps]]
* [[Parts interchange]]

== Shift knob and trim ==

The visible parts of the manual shifter include the shift knob, shift lever, shift boot, and console trim.

Cosmetic parts may be changed without changing the actual transmission. A shift knob or shift pattern insert alone should not be used as proof of the installed transmission.

== Service notes ==

When working on the manual shifter:

* Identify the installed transmission first.
* Inspect the shifter mechanism under the console.
* Check cable ends and clips.
* Check shifter bushings and pivots.
* Verify that the shifter moves freely.
* Check for console trim interference.
* Inspect shift cables at both ends.
* Verify cable adjustment after service.
* Do not assume all Fiero manual shifters and cables interchange.
* Diagnose clutch release separately if grinding occurs with the engine running.

== Notes ==

The manual shifter is only one part of the Fiero manual-transmission control system.

A complete diagnosis should consider the shifter, shift cables, cable brackets, clutch hydraulic system, transmission linkage, mounts, and actual installed transmission.
