Hey guys,

I have a side-shift transmission with all the required conversion parts that I want to put in my 1970 1.7. I got the transmission and parts from a parts car long ago.

Before I just put this in my car to replace my tail shift which is working fine, it there a way to test it without a full rebuild?

Who knows, I may be lucky with a fully operational transmission without having to rebuild except for changing out the fluid and any leaking gaskets just like I lucked out with the original tail shifter.

Any advice is much appreciated. (IMG:style_emoticons/default/beerchug.gif)

My recent experience says Yes - you can determine a few things out of the car / The way to generally test the gears is to run thru the shift pattern and confirm all are achievable with out anything other than the shift ball at the console and do this by bare hand / no tools. That typed,... you will obviously not be able to confirm condition of syncros and bearings much less dog teeth and sliders. To do that requires opening up the box and taking out the gear stack / a not to difficult task - at which point most-all is revealed. In my case (no pun intended),... I bolted up the box insight unseen, and drove the sucker for three years and am still driving it on a powerful 3 liter 6. Sometimes, one gets lucky and the 901 is extremely forgiving in most non-race applications. It is easy to R&I so I say put the box in and adjust all linkage with new bushings and cone screws and see what you have.

After the clinic with Dr. Evil a few weeks past, I now have another 901 as a spare with all good innards and a flipped H for higher speed at lower revs in 5th on my 6 3.0.

I will insert that transmission and sell the good box I currently have some day soon for something to do - but my current 901 is proven to be just as good with stock gearing - in my car currently / hope this helps.....

You really cant. You can move the shifter, and spin the shafts, and that is about it. You wont be able to detect usual failures like slider/band/teeth worn, broken blocks and bands, bad bearings, worn R/P. If you are concerned, pull the stack. Re-seal it is easy and worth while. Pulling the stack is simple, click on my link in my sig to the rebuilding service and it has directions for pulling and replacing.

Forrest, you saw my dilemma at clinic. The good Doc has reached out to help with another trans but since you are local let me know if I can buy your spare trans...no hurry. Let me know.

Factor in that you will have to spend $120 to ship it to me and factor that into the core price (IMG:style_emoticons/default/wink.gif)

Thanks guys!

Forrest...consider it done...a dozen raw and Geaux Tigers!!!

Dr. Evil...will do! Might as well pull the stack to see what I have. Worst case you will get an order for a DVD!

Good times! (IMG:style_emoticons/default/beerchug.gif)
