- Pictures are examples - All Transmissions are restored identically. I also offer the same restoration service for YOUR Muncie 4 speed, including shipping an empty custom crate with instructions to safely ship your transmission. Please call for details.
Select from: (
winning bidder
must
contact me with these (5) choices
before
transmission can be built and shipped
.)
1. Wide 1st gear ratio (2.52 : 1) or close 1st gear ratio (2.20 : 1).
(about 12% difference in 1st gear mph)
2. Speedometer drive on driver or passenger side of tail housing.
3. Choice of nuts (on studs) or bolts (in threaded holes) for shifter arm mounting on shift shafts. May be substituted with new universal shift shafts.
4. Your vehicle's rear-end ratio and rear tire diameter (if significantly more or less than 26") for correct speedometer gear installation.
5. Factory style 1/2"npt magnetic drain plug drilled, tapped, installed or not.
All transmissions are completely reconditioned mechanically and restored to like-new operation and appearance.
Restoring
your Muncie is available also. I will ship an empty crate to you to protect your transmission for shipping to my shop. Call for details.
NEW - ALL FORWARD GEARS
(see photos)
* Cluster Gear
* Input Gear
* 1st Gear
* 2nd Gear
* 3rd Gear
NEW 3-4 torque-lock slider
NEW 1" cluster pin
NEW front bearing support.
(smooth, like new, clutch operation)
NEW input, intermediate, mainshaft and cluster bearings.
NEW tail housing seal and shifter shaft seals.
NEW brass blocker (synchronizer) rings.
NEW gaskets and small parts (thrust washers, snap rings, etc.)
NEW tailshaft bushing.
NEW
Grade 8
(aircraft/race car quality) bolts or nuts and flat and lock washers for shift arm installation.
ALL NEW bolts with NEW steel french bolt locks on the front bearing retainer bolts. Clutch vibrations frequently loosen the bolts without the french locks and destroy the transmission by allowing the input gear to grind forward through the case.
ALL other parts are cleaned, glass-beaded, inspected and replaced if sub-standard. 1-2 synchronizer sliders have full-width engagement teeth. 3-4 synchronizer sliders are new torque-lock type.
ALL mating surfaces are trued for proper alignment and no leaks.
ALL threads are chased or correctly repaired with stainless steel heli-coils.
Jigs used f
or accurate drilling and tapping for heli-coils.
ALL transmissions have ALL factory updates installed including 1" cluster pin and gears, stronger late-model brass synchronizer rings and magnetic drain plug (will delete by request for original configuration). Case cluster pin holes are gauged and professionally bushed (if necessary) to return to the original, leak free, press fit on both ends. Most unrepaired or poorly repaired front cluster pin holes will leak continuously with the transmission full.
Main shafts are checked for straightness.
Lockout cam arms are straightened (if necessary) for smooth shifting. These are frequently distorted due to
aggressive
shifting and binding is common unless corrected.
"Mystery" Muncie 1st gear noise removed!
Fresh "select fit" on both synchronizer assemblies.
1/2 NPT Magnetic
Drain
Plug installed by request.
(Most Muncies do not have a drain plug. Changing gear oil occasionally will make the transmission last years longer). I recommend the first oil change after 500 or so miles. U
se an 8 point (double square) 9/16", 1/2" drive socket on the plugs (available at Sears), not vise grips or an open end wrench.
Transmissions are restored by an ASE-certified Master Technician with over 4
5
years of experience rebuilding hundreds of these transmissions. All cases are glass-beaded (very fine grit) and sprayed with clear lacquer for a factory-fresh appearance. N
O
welded repairs on cases. WD-40 spray is used for preservation until installation oil fill. 90 weight (or multi-viscosity with 90 weight in the range) petroleum gear lube recommended. Do not use GL-5 rated lubricants, as the friction modifiers inhibit synchronizer function. Additionally, GL-5 specifications include compounds that are known to attack "yellow" metals, such as brass and bronze. GL-4 lubricants are recommended, but becoming hard to find. Google "GL-4 gear lube" and the selections are obvious. Fill plug is delivered finger-tight; drain plug, if equipped, is very tight. Capacity is about 2 quarts. A 6 month warranty (except for abuse, which includes broken gears and other obvious mistreatment evidence) from the date of installation is included, up to 2 years from date of purchase. Transmission will be shipped in a custom, high strength, wood crate (see sample pictures). Will ship to lower 48 states only.
Foreign buyers may employ a U.S.
-based freight forwarder for shipping out of the country.
There are 231 parts in a Muncie 4 speed transmission. Each part requires special attention to detail for a totally correct rebuild. I leave no detail unattended. I will exceed your expectations.
A 0 core allowance is
available
for complete Muncie 4 speeds (except 1963 "704" cases).
A core is not required for the transaction.
A core is a separate issue, is completely optional and does not affect the selling price.
WARNING! Pilot bushings in the rear of the crankshaft MUST be
Oilite
Bronze
bushings or roller bearing. Offshore bushings are being sold at many parts suppliers that are CAST IRON, disguised as bronze with bronze coloring mixed in the casting. These bushings wear out rapidly and will destroy the transmission. If your pilot bushing is
magnetic
(or worn), it
must
be replaced with a non-magnetic oilite bronze bushing or roller bearing. Pilot bushing/bearing failure voids my transmission warranty. This failure is obvious when transmission is disassembled. I can supply the correct bushing for Chevy and other GM engines that use the same bronze bushing. If needed, request a
free
bushing when ordering your transmission.
