Transmission mount replaced
I changed out my transmission mount. I used the jack from the trunk to hold the mount while I was taking out the bolts and nuts and then slowly lowered the mount brace until I could remove the mount. Installation I used the jack to move the mount bracket in place as I installed the 4 bolts.
The old mount appeared to be in good condition with no tears.
The new transmission mount I bought from Ebay as part of a set that included the engine mounts (2) and transmission mount. The ebay listing was called "Motor Mounts & Trans Mount Set 3PCS fits 01-06 Lexus LS430 Automatic" and the seller is mounts_pro.

I haven't driven it much. I will know more when I get it out on the highway but I'm suspecting I won't really notice anything.
I believe the small vibrations I feel at highway speeds are due more to the motor mounts which I haven't changed yet. However I also wonder how much a cumulative affect of old suspension parts contribute?
So far I've changed the front lower ball joints, sway bar links, outer tie rod in and transmission mount. Within the year I'm planning on changing the motor mounts, all 4 struts (non air) and upper control arms.
My goal is to get this car driving like new again. Since I am planning on keeping it for a long time my 5 year plan is to repaint it and probably spend close to $2,000.

The rubber looks a little spongy, but other than that, it does look clean... Interesting.

On a scalle 1-10 how hard was it to get off the old one and replace ? (1 being easy and 10 being very hard)
My car is sitting with 240K on it and would be nice to get a little smoothness back into the ride... I was thinking about motor mounts too but, not something I think I can do in my garage..
I could jack up the car and put jack stands under it... I have a RX300 jack... same jack as on the LS430 but, goes a lot higher... I can fit the jack stands under the car with no problem but, cant with the LS430 jack.
You can get a RX300 jack on ebay for under $40...(my wife had an RX and I tried it and was shocked)

Interesting... Was the whole car jacked up when you did this, or can I just take the jack out of the car and crall under it to do it ?

If I did it again I would give it a difficulty of 2 on your scale.
You could just put jack stand under the front. No need to put jack stand on back. Just make sure emergency brake is applied for safety.
The motor mounts will take an engine hoist and need to have front and back of the car on jack stands. I would not jack under the oil pan to do this.

that is another way but I don't feel comfortable jacking under the transmission pan, even with a block of wood between the jack and pan.

I will like to know where you are getting a paint job on your lexus for $2,000. I will gladly buy a car I saw for $6,000 (2002 LS 430 with 70,000 miles) which is in bad need of a paint job.

Hi ELexis, which procedure did you finally use to replace the transmission mount on the IS. Did you use the jack under the aluminum bracket or under the transmission pan with a block of wood? Also, is the sequence of unbolting above is in correct order?
Thanks in advance for your response.

Hello Yamehoo, the procedure I used is stated here (reference reply #169 down) however, ended up going to service center to have the mount installed. Also, keep in mind this forum is for posts related to the IS-F 2008 – 2014 with an 8 Speed transmission. Hope the following assists you with removal / installation;
