Anyone know if a Zf5 will bolt into a 99-03 and if the input shafts reach. I don't see why they wouldn't since it's the same motor but probably good to ask before picking one up. Yes I'm aware they are weaker than the 6

early 99's came with the ZF5. so yes they will bolt rite in. you may need a 5 speed crossmember though

Thread Hijack!

What about the other way around? I have the ZF5 and would like to swap to a ZF6, as I have been told they are a stronger transmission.

Thoughts? Whatever I put in will be rebuilt before I put it in.

Thanks!

Thanks, @tjctransport -

After all I have read, I will stick with the ZF5 since there just isn't that much to gain. Also, I don't want to bother with a transmission cooler.

Except that I have a ZF6, so I will stick with that! :D
