Sorry, I'm certain this has been covered already, but I can't find it:
I have a 97 prostar 190 with 1:1 transmission. Manual says to clean trans filter and shows it on bottom of trans. I can't feel any bolts underneath where it seems to indicate they should be.
I'm guessing that this one really doesn't have a filter.... True?

Are you getting it confused with the transmission cooler filter/screen?

The entitled attitude is obnoxious.

Really didn't mean to come across as entitled. Just wanted help. Best as I can read the manual, it clearly says trans oil filter and shows it on the bottom of the trans which is completely out of reach. The manual covers 2 different trannies, so maybe it just applies to the one that's not mine, but it doesn't stipulate. Oh well, oil is changed and all is well. And, the manual doesn't even mention the trans cooler filter, but glad to know that can be something to keep an eye on.
Thanks!

sorry a little late to this thread. If a ZF Hurth 45 - the filter is located under neath the transmission. The repair manual in along with other decal art...

Here's the filter... http://www.michiganmotorz.com/transmission-filter-zfhurth-25456380-p-477.html

Thanks for all the info. My trans is a Hurth 450, but it looks just like the manual you provided. And yep, I can see (barely) where the filter is undernearth the trans, just where manual says.

So....can it actually be taken out without removing the trans? There appears to be only a few inches clearance between the cover and bottom of boat. And, I can't even see one of the bolts. Can feel it though. I'm not even sure I could get the bolts backed out enough.

Any words of wisdom are appreciated.

Any words of wisdom are appreciated.Can you lift out a floor section for more access?

I believe either you need special tools or pull trans to change filter.

Regarding question from Cloaked: I can actually get to it pretty well from the side, but it's the clearance underneath that seems to be the issue.
And to Mikeg205: I'm thinking that a trans pull is the only solution. I might could get the bolts out (maybe) but just can't see that there is enough room to even get the filter out after that.
Based on that, I'm guessing that I won't be the first to ignore the 100 hr filter cleaning ;)

I change my trans fluid every season - always looks brand new when I suck it out. I plan to pull mine at 1000 hours... when I do additional maintenance... unless I have another freakin' long winter like this year...
