Default 5AT: A detailed look at the trans used on 5AT Zs/Gs

I haven't seen these posted here before but I found them on a Titan site. The Titan uses the same trans as the Z/G. The links include a 3 part article on the trans and there is one attachment that has rebuild info for the trans. I see tons of people asking questions about their tranny and what it can hold but there doesn't seem to be a lot of info about the trans itself. Enjoy!

Rebuild Info

Excellent info Rob. It is a complicated trans to say the least. Heat is the killer. The "failsafe mode" is troubling but it works in saving the transmission from damage. I had it twice with my old transmission and that one now is in another car working extremely well.

I'm glad this info was worthwhile. It certainly does give us a look into why having a "built" auto is so expensive and tough to do.

Its good info, but I would consider it the "idiot's guide" to the RE5R05A. The FSM contains all this information and world's more, just in less layman's terms so it takes a bit more to understand. Still, a good primer for anybody new to this transmission who doesn't want to be overwhelmed.

Also, the rebuild info you posted is the general rebuild kit, not an upgrade kit. Here is the info on the Alto Red Eagle rebuild kits that would interest most people in this forum.

Thank you for adding that. For some hopefully those articles are much easier to understand than the FSM which can become cryptic at times.

I'm assuming the Titan uses a beefier TC and VB?

Also, I'm assuming that a Titan engine should bolt right up to 350Z 5AT, right?

Titan has a much larger torque converter and bellhousing that is designed to handle the V8's torque and abuse of moving heavy weight wiht load, so they won't bolt right up. But the internal clutch packs are identical to what is on our vehicle.

I have a modification on my maxima where I hooked up a switch to my line pressure solnoid to make it shift at full line pressure when I go WOT. Could this be done on my Z?

Yes the transmission shifts the same as if I upgraded my valve body. Saved me $400.

I'm also very interested in this if anyone could answer the question ajcool2 is asking. Hey aj dont you have a 5at z do you have any launch techniques you could share with me i understand you hold your own at the drag strip. Oh one more thing how does the valve body upgrade work their has to be a difference though don't you think between a switch on your solenoid line and the valve body upgrade.

This thread should answer most of your questions. Mainly post #33 and #34. http://forums.maxima.org/showthread.php?t=208756 Of course this applies to the maxima but hopefully some of the Z gurus can apply this to our cars. I know the main difference is that the VB mod always shift hard no matter what and with this mod it can be turned off if you want your smooth shifts back. I know someone with the vb mod in his maxima and he says it shift the same as my car. I've been using this mod on my max for 2.5 years with 172000 miles on it and my transmission has been fine. As for the my launching techniques I'll pm you.
