...Toyota Tercel? Got a used tranny to replace one that is stuck in third gear. Will most likely reuse clutch (only 2 yrs/14000 miles highway on clutch). Just want to know estimated time from start to finish to change over tranny. Thanks ahead of time

It really depends on your ability. Allow yourself 4-5 hours. Since you had to ask I'm assuming you havn't done many.

adjusting the pressure plate and bleeding the clutch cylinder, about 2-3hrs if your familiar with the configuration. but thats if you DIY.
