Your car should already have a tranny cooler in the radiator, but yes the cooler the tranny the better. So you could add an another one to make things even cooler. As for the oil cooler, i don't think that your oil will ever get hot enough to cause damage, or be burnt. Also you want your oil to be as hot as possible to that it is really thin and make more power.

No, no transmission cooler on a manual, and there's not really much point to trying to add one.

Funny, a lot of the L98 cars came with them from the factory, so you know that GM believes in them. Not sure if they're truly important or needed, but I'm not going to remove mine anytime soon, nor am I going to add one to every car I got, unless I got plans to hop it up a lot.

There were thousands of L98 and G92 LB9 with KC4....
normal oil temp is around 250-260 degress while the water temp is right around 200...haveing very hot oil will give you a tad more power, but what about thermal breakdown...im to lazy to go into the details but i dont need to....HOT oil is not a good thing, thats why there are oil coolers...and id hardly call a stock L98 a "race car"....VERY warm oil (225 degress or so) is what you should shoot for...for a "race car" the hotter the better becasue your not after reliability, and even then the 50 degress in oil temp difference wont get you that much more power, but it WILL cause less oil life and more wear and tear...
if you have one why not use it?....

Engine oil coolers are real neato for long trips and sever service use. Other then that they neither take away or give anything to engine life or performance. Ive got one on my bird because the adaptor and hard lines were free.
I Beleive its honda that uses a transcooler for thier standard transmissions so It could be done just isnt worth it.

Maybe for transmission fluid, I don't think I've ever seen an oil temperature below 250.

I think it was Car Craft that did an article on oil coolers and the reccomended temp's for oil. They listed 135 as the "optimal" temp. as did some other sources.

the 400 i had in my old 82 would always have low low oil pressure once it got warm and im idling..... sure it was fine above that, but being younger, i hated and feared for the life of my engine when i saw low pressure and coolent temps over 200 lol..
anyway, i stuck a oil cooler on the car... not only was the pressure at idle better, but the oil looked nicer when i changed it...
1/3rd of your engines cooling is from your oil. it makes sence to have a nice oil cooler.
if you're not running longtubes, i reccomend a cheap spin on adapter between the oil filter and block, and a nice cooler up front.
if you have longtubes, it wont clear... with longtubes, id get a "filter relocation kit" and relocate the filter, then run the cooler inline with that.

Okay, Where in your oil system is the oil temperature sender(aka sensor)? What other sender are you talking about?
Also are you sure the temperature reading that you have quoted as the recomended etc is 135*F and not 135*C. Reason I ask is that 135*C is something like 275*F which is hot but closer to what might be expected.

I'll risk a guess that his oil temperature sender is in line with the oil pressure sender.
If that's the case, it's dead-headed and is not reading the temperature of the oil that is circulating through the engine.
Keeping the oil cooler helps reduce the oxidation of petroleum-based oil and viscosity index improver additives. The '90 Bonneville SSE I got with 104k on it had one of the cleanest engine internals I've seen in an engine that used petroleum-based oil. The system they used for that model was different than the 3rd gen system, though - more like the tranny cooler that routes the oil to a heat exchanger in the radiator tank.
A really inexpensive alternative to an engine oil cooler is synthetic base engine oil.

My factory oil cooler fits no problem with my heddman longtubes
