Manual Transmission Q's

[miner88]

Few questions concerning the transmission system for my manual V6 88 4R. I have a leak in the seals where the transfer case and front drive shaft link up I think so I need to replace that. I also need to install breathers in the appropriate areas so I don't blow them out again. So my questions are what kind of fluid do I need to throw into the front and rear differentials, the transfer case, and the transmission? Where is the plug and drain whole for the transmission and transfer case (or are they connected and only have one?) Finally where should I throw breathers in (front, rear, transmission, transfer case?) Any helpful articles that you guys know of are appreciated too. I don't know much about this part of the vehicle so I'm running on a low tank of knowledge.

Thanks

80-90 weight gear oil in the diffs. GL-4 in the tranny. Breather on the diffs defiantly, tranny and t case if you can get to them.

Use the search feature, plenty of write ups on this topic.

Before we can tell you what to put in the trans, it's really important to know if it's a manual or auto trans, there's a big difference.

As for the diffs, 75W90. About 2.5 qts for the rear and 1.7 qts for the front.
