He really shouldn't have to change his internal filter. It's just a screen. There's no reason to drop the pan. He doesn't even really need to change the fluid for a while.

Wow.. I was considering converting over to a manual transmission. But now I might wait to see how things turn out here. With all the mods and upgrades done how does the transmission shift on everyday driving and do you expect any failures as seems to be the case with other professionally rebuild and or reconditioned 4eats?

I'm not sure who these questions are directed to but my opinion is great and no

long....

so do you think with the mods and upgrades in the 4eat... is this just as good as going to a 5speed manual?

The built auto certainly works better and races better than a manual. The only reason to get a manual transmission is because you want one.

doesnt the auto also use a computer?

longassname · #**112** 12-04-2007, 08:56 AM

Yes the auto is controlled by a tcu (transmission control unit)

does that need to be upgraded as well? or is it just fine the way it is?

longassname · #**114** 12-05-2007, 01:10 AM

i'm sure we could do some good stuff tampering with the tcu software but the mechanicals trump that. It takes more clutches, higher apply pressures, and higher coefficients of frictions to pass more torque.

Does the built auto still have the same shift RPM as a stock trans? If yes, then my next question is can it be raised at all?

longassname · #**116** 12-05-2007, 08:10 AM

That would be something you would need to change in the tcu firmware.

how difficult is that? what about changing the torque converter for higher rpm's or is that also controlled by the tcu and not needed to be changed?

longassname · #**118** 12-05-2007, 04:29 PM

neither I nor anyone else that I know of has gotten into the tcu yet.

There are places that will remanufacture a torque converter for a higher stall speed. I'm not personally interested in a higher stall speed. With my transmissions I supply an oe spec torque converter from daaco.

the guys have gotten into the ECU and played with it already. just no drop in ROM socket for permanent changes

Tom

There IS a space for a ROM socket on the TCU circuit board. I reckon it can be chipped just like the ECU.
