[AJD] H Tranny and manual

[Bill Brueck]

Thanks, Greg, now I can feel like I did the right thing on my H project 
instead of feeling like I was too cheap to buy the shop manual, LOL.

I remain amazed at how much useful information is contained within the 80 
pages of the IT manual.  With the JD parts book (I bought the inclusive CD 
when it was still available from Deere) and occasional reference to the IT 
manual my H came all apart and back together just fine.  Within those slim 
80 pages you get A, B, D, G, H, M, and MT!  It really was a good piece of 
research to know which models they could combine for each procedure.

Is anybody aware of any blatant errors in the IT book?  I found it to be 
right on, giving them some allowance for changes along the way for the 
model.  I mean, you still want to apply common sense to your work.
