NewbieTranny ID Question

[bigredblzr]

Tomorrow I'm going shopping at Pick N Pull for a 700r4, however, I don't know how to tell it apart from a TH-model or a 4L60E. Are there any hints like the 'Ears' on 10bolts, or do I have to have the year, and model of the truck to ID the tranny?
Thanks,
Nate

The 700r4 and 4l60 until electronic are basically the same thing. If you look at trucks from say 93 and back it wouldn't matter anyway. The important thing to look for are trucks with the trans still installed, smell the fluid if its burnt smelling or dark look at another. /forums/images/graemlins/k5.gif

Ahh, good point, I didn't even think about smelling the tranny, though it may have occured to me tomorrow. I just found a page on Chucks Chevy Truck's site that showed the different shapes of tranny pans from the TH350, 400, and 700r4. Very helpful. Thanks again!

Well if you got a tape mesure the length of a T-400 is24 inches the 4L80E is 27.5 inches the 700R4 is 23.5 inches and I think the t-350 is even shorter tese measurements are bell housing to were the adapters bolt to the tranny. count how many times it clicks on the shifter to see how many gears it has start in park and go to first that should narow it down I just know them by sight now. Check youre local tranny N gear shop they have those poster with all the shapes of pans on different tranys years and models I used to have one how I learned. /forums/images/graemlins/crewcab.gif /forums/images/graemlins/k5.gif
