99 Denali

[josetizapan]

Hello i have a question.

I have a 99 Denali and i replaced the engine with a 117,000 miles in it and my original had 150,000 but 2000 miles later my tranny went out it dont have reverse or third and four gear.

Well ? is would a 350 turbo transmission would bolt on with minimal modification?

Thanks in advance

Why not just go with the 4L60, or whatever it came with? A direct swap requires no modification...

Good luck!!

Because i can get one for a few hundred dollers but if its to much work i just get mine rebuild and that would have to wait because a shop here charges me $2000 to rebuild it.

I have no idea. If you don't get any help here from others (many mechanically inclined here), my next best advice is to go to a junk yard, and pull the parts, and measure them side-by-side.

not worth the trouble man. get a 4l60e.

The Th350 would bolt up no problem only thing is that your computer might be going crazy since the th350 is not electronic. Also 4l60 has 4 gears with over drive and the th350 only has 3 gears with no overdrive. Not worth in my opinion just get another 4l60 from junkyard.

TH350 is a dumb idea, it will cost more in the long run (tcase adapter, lengthen drive shafts due to shorter trans, crossmember difference, computer problems. etc....), stick with a 4l60e and be happy, besides, a TH350 is not that great of a transmission either.
Also, you will have to modify throttle body to accept the TH350 kick down cable.

Thank You guyz.

Would it be worth gettin a transmission from the junk yard i heard ppl say that its better to rebuild then to get one from the yard?

depends on what your getting from the yard, some times quality is more important the cost, other times not. i had mine rebuilt and im still living with problems, so its not always the best. But you might get a lemon from the yard you never know, on a side note some yards warranty parts.

Does anybody know how long does a transmission shop take to rebuild a transmission?
