Re: 4L60E rebuild, no 3rd gear
When the 3-4 Clutches are smoked.....But you still have 3rd Clutch apply circuit integrity......
*3rd clutch apply oil knocks the 2-4 Band off via the 3rd clutch accumulator behind the 2nd apply piston.
*With no 3-4 clutch holding ability.....The trans will now be in 1st gear causing a big Flare.
If it just stays in 2nd gear.....That could be a 3rd Clutch apply circuit integrity issue, Like a big leak.
