Turbo question

[Shimy87]

I plan on putting in a locking switch, my question is how will know if its trashing something?

 I meant get a converter that was designed to be locked.  not just a switch.
 triple disc. 5 disc.

It will put trash in the fluid and eventually need a transmission.

You will know it is trashed if the rpm drop when you lock it and then jump back up.  The transmission fluid will be dark and stink, and the pan will be full of clutch material.

If he told you it would not be good, you can bet it would not be good.  I don't know who he buys his converters from but a 9.5" converter does not have a lot of clutch area in it due to it's size but some are built like the 911 converter which has the clutch area of an 11" converter tacked on to the back or like the vigilante that I have that has multiple clutches in it to handle the load.

You ignore his advice you might be in for a transmission rebuild.  Usually on a 11" converter, they will last a long time on an 11 sec car.

This is just 1 option.

I have decided to try to find a used slic and have a Dave Husek 3021 converter on order. Read tons of positive stuff on them and talked to him quite a while.

should be an improvement.  Should be about right your needs

[Steve Wood]

As far as I know, this is still the required procedure to modify your lock up transmission to a NLU converter    https://www.gnttype.org/techarea/transmission/cvt_to_nonlockup.html

I don't pay much attention to transmissions so things may have changed.


Never mind, you probably ordered the Lock up version so you don't have to do anything

[Shimy87]

Well, got the new converter installed yesterday. Really like how the car drives now, and turns less rpm at highway cruise also. Did the brake til boost test and its 2572 rpm. On the street it spools very quickly so so far very happy. Hope all this goodness keep going when the track opens!!

[Steve Wood]

Sounds good.  Can you tell a difference in how solid the lock up feels?  Asking because you said it pulls less rpm.

[Shimy87]

It seems like its strong. In relaxed driving, somewhere between 50 and 60 it locks and rpm drops from about 2200 down to 1800-1900....hard to be exact with the digital tach and didn't watch on sm.

[Steve Wood]

the lock up speed is programmed into your chip.  The ecm grounds the wire at the programmed speed and locks the converter.

It sounds like it has a good firm lock up compared to your old one which is good.  I think the car is going to run much better now.
