Rebuilding theGM / Chevy's 1993 through
2008 - 4L80E
4 speed Automatic Overdrive Transmission
   
This 5 hour twin disc production shows hands-on, step by step treatment of
building GM / Chevy's 1993 through 2008 - 4L80E 4 speed Automatic Overdrive
Transmission.
All components and assembly are shown up close and with great detail so anyone
can understand.
The most complete and exhaustive video ever produced on the GM / Chevy 4L80E 4
speed overdrive automatic transmission.
The production starts with disassembly and inspection of all parts and
components. Cleanup then the rebuild starts with a bare case. First component
rebuilt is the direct clutch and output shaft. All steels and clutches are
removed then the spring retainer to the piston. The direct clutch with piston,
clutches and steels are rebuilt and reassembled and checked for clearances.
Then that complete component is installed back into the case.
Next the center support and planet carrier are rebuilt and installed. All one
way clutches are taken apart, cleaned and reinstalled. All spacers, shims,
roller bearings and Torrington bearings are inspected, cleaned and reinstalled.
After the center support with the planet carrier is installed you install the
anti-clunk spring and then the center support snap ting. The low - reverse and
forward clutch drums are rebuilt by removing all the clutches, steels and
pistons and placed together and installed with the proper bearings into the case
on top of the center support.
Both low-reverse and overdrive bans are installed. Then the intermediate
clutches are installed and checked with a depth gage to make sure all clearances
are correct.
The front pump is disassembled and all gears, piston and stator are inspected
and rebuilt with new bushing, lip seals, stator sealing rings, converter seal
and assembly gel. Both 1-2 and 3-4 accumulators are cleaned and resealed and
reinstalled. You will learn what bad clutches and steels look like and when to
replace them.
Where the valve body check balls go, when to replace bushings, and what other
parts you need to replace with new. The low-reverse & overdrive bans servos are
resealed and reinstalled with close attention to ban connection. The front pump
is then installed with guide pins and torqued.
Next we move into the valve body with cleaning, checking and reassembling. A new
seal is installed into the shifter lever and the valve body is installed and
torqued. Filter and pan. The converter is inspected and found no good. A
replacement is shown and you watch the proper way to install a torque converter
into the 4L80E transmission.
Then, off to the dyno shop and you watch the transmission you helped build go
through dyno testing and it worked perfect. All 4 gears and the overdrive
lockup all worked perfect so you understand how all the parts and components all
work together and that you built it right.
All clutches, drums, assemblies are shown up close with great detail where snap
rings go, removing snap rings. All torque values and clearances are shown too!
