[Toyrolla]

Ok...

First off, let's understand the following...

The torque converter is the unit that acts as the clutch when the gears shift in an automatic tranny. You have 3 primary gears, plus the 4th overdrive gear.

Now, the torque converter is what shifts the gears, which in turn sends the signals to the speed sensors, which in turn send the info to the transmission computer, which in turn sends the signals to the ECU.

In other words, you can tell autoshop101.com that Toyrolla from the Toyota/Camry based forums personally says to kiss my ass.....

Dumbasses....
They don't know jack-bone about Camrys.....those %@$#%@$%!!!

Apparently, you are losing proper fluid passage/lubrication within either the torque converter or the tranny itself. I would guess the torque converter first is crapping out before the tranny, because the factory torque converter is not shifting at the default stall speeds set, which as a result, is not shifting the gears properly within the tranny.

Unless you replace the torque converter or the tranny itself, the slushbox problem will not be resolved.

Save yourself the trouble and convert it to manual.

For the same amount (or less) of money to fix your problem, you can shift 5 gears at will......

I'm telling you this because I changed the auto tranny in my '88 I4, which in my opinion, is the worst judgement call I ever made...

For the same ballpark cost, you can get a clutch reservior, a clutch pedal, and hardware to run 5-speed....now you're moving!

Good luck in resolving your problem....
