dear forum,

After a year of flare transmission, between 2 and 3,

Did replaced k1 spring, changed, ATF and filter,

Work well for two days,

Than start to heisted hills,

flat road can drive 65 miles,

any ideas?

288,000 miles,

looking at corolla,

Unless you're slipping badly (high RPM, but no downshift caused it) you have a horsepower problem, not a transmission problem. The SDL should be able to hold 75-80 up a 16% grade (which is pretty steep) without shifting out of 4th and without requiring you to mash the pedal into the carpet. Check/replace fuel filters and check boost pressure at the ALDA.

it feels like a clutch is slipping,

How do you determine that? If traveling a constant speed and you put your foot down without engaging the kickdown switch, do you suddenly get a HUGE increase in RPM without a resultant downshift? Remember that your transmission does not have a lockup torque converter, so a couple hundred RPM variance is normal from light cruising to hard accelerating.

the car revs high, Not much power to the wheels,

Maybe low pressure in the transmission???????

Maybe coolant enters the transmission line, from the radiator????(4 years old)

i am puzzled,

Check your fluid level

Fluid level was ok, smell of burnt ATF,

drained the torque converter,

Brownish smelly ATF,

Did bring it back home,65 miles/h,

Bought a Toyota corolla,

same color......
