For the diffs, 7qt will do. I'll assume 75W-90 for both now. The tcase has been an item of discussion. It calls for ATF, but many are using the 5W-30 motor oil. 2qt to replace or 3qt to overfill thru the speed sensor. We also have the pump to make it easier to get the fluids in. For the tranny, you have two choices, either the ATF or the torque-drive. Your model year called for the the dexron 3 product. Either of these will work. You're probably familiar with it, but torque-drive is a replica of the Transynd. Sometimes I'm asked which I would use. I like the ATF. It's a newer, improved product. Meets the demands and even runs a little less..but either is fine.
Also, how do you plan on doing the tranny? A full flush will take 13-14qt. If just doing a pan drop, 8qt will do.
Let me know tranny fluid choice and qty. Also which fluid for tcase and qty. As for diffs, as mentioned, I'll assume 75W-90 unless you might be thinking 110 in the rear.
ONce I have those vitals, I'll shoot you a price.
Thanks,

im doing a transmission flush and torque drive would be nice. the transfer case im going to put ATF and 2 quarts also. Rear diff 110

i think that covers what u want to kno? -

Sounds good. I fogot to mention that the torque drive is fine for the tcase as well. That way you only have to order one type for both and a case of 4 gallon should be just right to do both.
I'll price that along with 2qt 7eW-90 for the front and 4qt 75W-100 for the rear.
thanks,

Appreciate the kinds words. I must also tip my hat to RSWORDS. He made a referral for me today. A business aquaintance of his asked him where he could get some AMSOIL and he referred the gentleman to me. It's things like that that make this site special.
Thanks Bobby!! -
