Did you do any maintenance to the new trans before installation ? Fluid swap / Filter swap ?
No, I just kept clearing the codes and they would come back on. I talked to my brother in law who is a mechanic and a neighbor who is a toyota mechanic and they both said Im going to need to change the tranny out.

I am not sure of the similarities between the 07 IS350 and 07 RX350 transmissions. With that said, i also had to do a transmission in my RX350 at about 110k, it doesn't appear to be common but it definitely happens. I had mine rebuilt and it cost me way more. You did the right thing, nice work!

I believe the rx is front wheel drive. The Is is rear. Not sure which one would have been easier to do.

Doubt it. I think all the 2IS 6 speeds are tuned the same (AWD models might be tuned slightly differently)

Major respect for swapping the transmission out yourself @OP. Best advice from now on is to just flush the fluid out every 50k miles to ensure it will last longer than 120k miles.

How much do you think you saved? Anyone know the average cost to put a tranny in the is350? Not dealer but local mechanic shop that deals with tranny installations.. I have 90k on my 350 and so far so good I hope I won't have to deal with this in the future.

Most people have a lot of miles on theirs so Im sure you will be fine. Im not sure on price from a tranny place, $2500??? Wasnt an option for me.

No, I meant for the new transmission.. While it was out of the car, did you change the fluid or drop the pan for the filter.

No, we were on a time crunch to get it done before the sun went down. The torque converter must have had fluid in it because it only took about 3 1/2 quarts. We should have done it all but didnt.

Did you need to remove the driver side header to get the starter out? Also where do you unbolt the driveshaft at mine has two guibos one in front and one in rear. I was trying to avoid dropping the exhaust if possible

Didnt have to remove any of the exhaust or steering linkage. Did have to remove the starter in order to get the flywheel off and the tranny support bracket. The 3 or 4 bolts on the top are the hardest part to get out, 1 person over the top of the engine reaching down so that I could hand the 17mm with lots of extensions on it and break them loose. All in all we said it was about a 7 out of 10 for tough jobs. I needed a new transmission because ours was slipping during shifts. If you gave it alot of gas it would slip but if not too much gas it was fine but Im sure it would have got worse. I was also getting transmission CEL's. Bought the WS fluid from Toyota. Glad we did it because we saved thousands.
Mine is a 2007 Is350 with 128k miles on it before we put in the new (used) tranny.
