Manual transmission that is in gear-YES
When the input shaft is locked to the intermediate/output shaft
The rear, or tail shaft, of a transmission has a seal around the output shaft. The drive shaft will have to be removed and the seal replaced.
The sector shaft is the secondary or indirectly driven shaft in a manual transmission. It typically houses the "driven" gears along with reverse, although newer transmissions place reverse on its own shaft.
most likely worn output shaft bushing worn
Only difference is a bearing in the end of the cranksaft to support the input shaft of the manual transmission.
crank shaft sensor is near the oil filter. I have the repair manual but I am unable to past the page in here.
Most 3 speed manual transmissions without overdrive have 2 shafts, a mainshaft and a counter shaft or ( jackshaft). The main shaft is the shaft that the drive shaft is coupled to by a universal joint at the output of the transmission. When the transmission is in 3rd gear the output of the transmission is the same RPMs as the engine or the input of the transmission. So in 3rd gear or 4th gear in a 4 speed the mainshaft becomes as one from the input from the clutch to the output to the driveshaft
Go to NAPA and buy a Repair Manual.
A standard cab has a one piece drive shaft.
3,because the gear ratio in a manual transmission results is a gear ratio of about 3:1 for first gear.
