Oil/Fluid and Battery Questions

[FNG90-195]

My car is still at the shop where I initially saw it. It was a customer's car in for repairs over the winter (starter motor). I haven't brought the car home yet. Before I do, I would like to have the shop change the fluids, as there are no service records with it, or even a glove box manual to tell me what to use.

From reading a number of threads, I have determined that I will be using the Amsoil AMO 10W40, Bosch filter, and green antifreeze with glycol that meets GM 1825specs. (did I get all that right?)

Now for my question: what to use in the transmission and differential? what weight, and is it synthetic?

Also, I just thought - is there any kind of a filter or screen in the transmission?

I know I need to replace the battery as well, and I will use an AC Delco. Can you tell me the group and model # of the correct battery?

Anything special I should tell my mechanic before he proceeds? He has a C4 himself, and is pretty knowledgable, but I'm concerned there may be some special things to do or worry about. I've never had a car as advanced as this. I usually worry about replacing rotor and condensor and setting points!

Any advice would be greatly appreciated.

Thanks

Welcome aboard FNG and congratulations on acquiring the Z
Here are a couple of previous posts that may be of some help:

Regarding the transmission there is no screen or filter to worry about just drain the old fluid and refill it with Castrol TWS 10-60W from your local BMW dealer parts department and ignition system is all solid states so no points to worry about either.
The rear end you will have to pump out the old fluid with a hand pump through the fill hole then refill. Many of us use Mobil 1 75-90 and add a plastic bottle of GM posi fluid.
You got to like a guy who knows where he stands. You're in the right crowd here pal and you won't be known as an FNG for long.

I appreciate the quick response. I checked out the threads and now know what to get, but I forgot to ask how much of each do I need? I think I read somewhere 8 qts of oil for an oil change, (is that right?), but I have no idea how much Castrol TWS 10-60W or Mobil 1 75-90 to get. I assume the GM posi fluid comes in a 1 L or 1qt. bottle? I will pick up all this stuff myself and deliver to my mechanic. It'll save me some time lying on my back on a cold concrete garage floor!

While I'm asking (more) questions, are there reprints of the glove box manuals available that will give me this information? It would also be nice to read up on what buttons do what, and when they should or shouldn't be pushed.

I don't think I would ever undertake a major rebuild, but I usually do my own servicing and brakes, suspension, etc. Is there a service manual out there that provides that type of information for someone who needs jsut about every step laid out for them?

Once again, any and all comments appreciated.

Thanks

The trans takes little more than 2 containers of fluid,dont know the capacity of the bottle and you want to look into a Helms FSM,Helms is the company.

Welcome Mark...
Changing the coolant can be tricky on the LT5...does your mechanic know the protocols for doing this work... very different from the L push rod type engines.

How many miles on the ZR?

No 'screen or filter' for tranny.

Also add the slip diff additive first prior to gear lube.

On the trans fluid. zfdoc says to use this stuff and you can only get it at a BMW dealer. It is motor oil for an M5 I think? Anyway, it comes in liters and you have to buy three the first time round, you will only need two the next coupla of changes as it only takes 2.2 liters to do a change.

BMW P/N : 07-51-0-009-420 oil in NYC/metro area it costs $14.00 /liter
Castrol TWS 10w-60 synthetic motor oil.

Thanks all. Between the web sites and threads and the information from everyone, I think I have everything I need. Michael, the car has about 47K on it. Regarding tricky coolant change, he has a machine that pumps out the old and pumps in the new after a flush. I think it hooks into one of the heater hoses. If the old stuff looks pretty good, I'll ask him to just flush with water before refilling.

Any idea if this type of equipment will deal with the tricky part, or are we still likely to have problems? If there is a good chance I will have a problem, I'll get him to test the old stuff first and determine whether or not it actually needs changing.

The car has been through a number of owners over the years (5 or 6 I think), and I have no idea what has been done to it, so I wanted to start fresh with everything if I can. Cheap peace of mind.
