OK, I admit it, I need help. Had this trans for all of last year, never had it in high gear, now I need it to be. Runs in reverse, nuetral and low gear just fine, but won't go into high gear. I've checked all the obvious things, linkage, vaccum modulator, all the valves in the valve body are moving easily.

I am going to go through the governor weights for free movement, but I found something that I suspect. With the help of a book, it looks as though the valve body is for a rear pump model. My serial number shows that mine is front pump only. I'm not sure if you can put a rear pump into this case, I think so, but haven't checked yet. Will this valve body still work, if I remove the check valves that are required for a rear pump model?

Any help is very much appreciated.
