About to buy '07 tran for my '99 GTP ???

[90210GTP]

I need to get a tranny for my GTP. I have posted and had some response on another GP forum about using newer than '03 trans in my car. I am told I can use a non-tapshift unit from '04-'07 just fine, as long as I have correct bin put into pcm and may have to convert fluid line hookups. So what I am looking at doing is getting a '07 trans and getting a new DHP set up for the '07 tran and my '99 motor. Does anyone here have any opinions on why this would not work, or any other suggestions. One guy on the other forum says he already has an '06 tran in his '02 GTP with no problems. Just looking for more info before shelling out the money. Don't wnat to end up looking like a :th_jester:. Thanks for any responses.

What does Dave say?

I didn't ask him about it yet. I just spoke to him yesterday about diagnosing my current problem and found the broken forward apply band that he suspected. I may call him, I just hate to take too much advantage of his free advise.:th_winking: Maybe he'll respond to this post.

I had originally read a few posts about it being doable, but I thought I would have seen a load of guys saying it was a no-brainer if it was accepted practice for our cars. I just went through some time and research about using a 3400 out of an '05 impala for my '98 Transport van. I had been told by parts place that it couldn't be done, but after hearing from some guys about their V6's I bought one and had only 2 sensors too swap, as well as use my throttle body (for the linkage) and it fit perfect. That's why I'm hoping I can swing this swap, since I can't get anything local and they all have WAY too high miles to make it worth it.

Likely it is very doable. Only reason I'm not familiar is because I haven't had a need to try yet. :th_thumbsup-wink:
