Those were the 12,000 lbs. Rhino ramps which have a 6.5" lift. I do remember it being a very tight squeeze under there.

As for telling which, i think youll have to drop the pan (see the first post):

Few my post about which kit to get. theres a few different kits you can get that i didnt mention aswell.. just look on the rostra website and search for either a340 or a341 and then find the kit that you want.

Thanks bryan767! That helped out but I'm still confused. I replaced my two shifting solenoid's (Toyota oem) so I am no longer having hard shifting problems but my od light still flashes sometimes. What is going on? And also what does the lock solenoid do?

What a great DIY!!!!!....I am about to do this for a friend and he purchased the Solenoid from Lexus and it only comes as one unit. He has a code 63 indicating to change Solenoid number 2.....if anyone can tell me from the picture in this thread which one is the #2 Solenoid I will greatly appreciate it.

Does anyone know if this guide will work with a 1995 SC300? I assume it is pretty much the same thing even if the trans are slightly different. Needed some guidance before I head to pick n' pull though.

Had a quick question before I purchase solenoid from Lexus.

My 1995 Lexus SC300 is throwing a code 62, bad solenoid number 1.

The first issue at hand is whether or not I need to replace 1 solenoid or 2 of them. It seems that the A340 for our cars has two different set ups which I will show post diagrams of.

So how do I tell which transmission I have and which solenoid to replace?
