Stall question Next week I'm having my transmission rebuilt and will be adding a yank4k stall. Car is currently tuned by frost for the headers and intake. Will I have any issues driving the car home without it being tuned for the new converter ?

when i did my converter i was told by my tuner not to drive the car when i put the 4k converter in so after the install was completed he came out to me and did the tune, he was telling me that if i drove the car without getting it tuned i could burn somthing up "cant remember what he said exactly would burn up" but i build motors not transmissions so i took his advice
It should be fine but it may throw a code because it may think the transmission is slipping. If it does it may go into limp mode which will cause it to not to shift right and sometimes only have 2nd gear . This is what the tuner is talking about . There is a couple different codes he will have to disable and have to adjust your lockup speed and shift points. I wouldn't drive it anymore than I had to before it's tuned. If you have to drive it and it throws a code and acts weird unhook the battery and clear the code.

The 2001+ cars are more sensitive to this, having the issues mentioned in the post above. The earlier cars don't tend to have this condition. When I first put a 3500 stall into my '00 car, I didn't bother to tune for quite a while (this was back in 2001, tuning options were very limited.) Everything worked just fine, no limp mode, nothing burned up or got damaged. I drove it for thousands of miles that way. The lockup feature will also work fine on a stock tune as long as you don't have any misfires (e.g. an aftermarket cam, etc.)
Somewhere in that 3500-4000 stall speed range is where the later cars tend to throw codes with a stock tune. You didn't mention what year your car was, so that might make the difference regarding what issues (if any) you might see.

My very late 2000 model did fine with a 3000 stall, but when I went up to 3600, it started throwing codes and going into limp mode when I did burnouts at the track. I ended up having to tune out some of those diagnostics to get the problem to stop - which is to say, that with a 4k stall, you are very much likely to have to do the same.
The SY3500 I had from Yank gave me no such issues with a 100% stock tune on my 05/00 built 2000 car. Burnouts, racing, street driving, etc. - never any codes or limp mode stuff. Only slight issue was a bit of idle surge when sitting at a traffic light in gear (which mostly cleared up on it's own with an idle relearn, but never fully went away until I did additional tuning).
I really don't remember this being a problem for any of us with stall speeds of 3500 or less on the 2000 or earlier cars in those early days when tuning wasn't readily available. I do recall several guys encountering this with 2001-02 cars though, even at 3500 stall speed.

0757 burned me a bunch of times. Would cause a loss of 1st and 4th. You could pull over and cycle the key and it would reset. I would recommend a tune yes.
