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?

 

[99COOP]

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.

 

[josetizapan]

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

 

[Superman84]

A well capable shop with all parts in stock should be able to get it in and get it back out no more than a week. maybe less if they not to busy

 

[josetizapan]

Ok because a shop quoted me around 3 to 4 days and $2000.

 

[cmcarr85]

I just had mine rebuilt for 1200 in about 3-4 days. shop around craigslist they are all over for about 1000 here.

 

[josetizapan]

There's only two shops where i live and one of them has a bad rep and its only $200 cheaper and the closest city is about 40 mins and even there its only bout $300 dollers cheaper.

Oh and there doing all the work removel and install.

 

[99Yukon_Z71]

All depends on the volume they have. My buddy R&R my 4L60E in 2 days and with performance parts that I purchased for him. I personally think you should go to a tranny shop and ask for labor ONLY to remove overhaul and reinstall the tranny, while you get the parts. I just went that route because I have a heavy foot, tow alot and do not want to mess with more tranny problems in the future. I paid around $1600 after all was said and done and thats including all the Heavy Duty clutches, corvette servos, alto red eagle clutches, sonnax valves, HD band, transgo shift kit etc...

get a re-manufactured, NOT a re-built. IMO. i have a 99 denali also and same thing happened to me,no reverse, i got a re-manufactured one and got as many upgrades the shop could do,teflon belts,shift kit ect. loving it.
