2006 is 250 transmission
Can anyone out there might be able to
answer me this question. So I have a 2006
Lexus I S2 50 I did a transmission swap
and the dealer told me that I have to take it
to them and pay them $180 so they can
relearn the transmission to the computer of
Does anybody know if this is true the
reason I'm asking is because I want to be
sure of the situation I drove the car and It
feels fine so hopefully I can get some
answers thank you and have a good day
If your not having any problems, then if it aint broke, don't fix it.
Well the shift points are set by the computer, so if there is any variation between your original tranny and the replacement gearing ratios those shift points will be off.
To kenf so if all shift good and alll I shouldn't do anything
If the new tranny's gearing is identical to the old, you're all set, if it has very slight difference, it may feel like it is running the same but shifting may be later or earlier than desired, one effect from that is a loss of gas mileage. If it was radically different you would obviously notice it right away. Your VIN number can tell you the gearing of your old tranny, but to get the gearing of the new tranny you'll either need the VIN of the car it came out of or take it to a tranny shop and let them hook it up to a diagnostic machine. But then again, you say it's running fine, so why bother?
