Smile 190e 722.4 help. questions

ok the problem

1. wont shift in to 3rd and above.

what i have already done:

1. checked and replaced governor gear. it was not damaged or broke but the part was cheap so while i was down there i replaced it.

2. took off valve body, cleaned and replaced little valve seals and misc. parts

3. replaced vacuum modualtor cap becasue the old one was cracked, probably leaking air and casuing pressure issues.

4. disconnected the kickdown solenoid....nothing

5. checked the secondary pump and it appeared to be fine, moved freely and there were no parts stuck in there.

6. the b1 band appears to be intact, when i squeeze it together the whole thing moves leading me to believe it is in on piece. i also wiggle from side to side and the whole thing moves as one piece.

what i have heard it may be

1. b1 piston

2. secondary pump? are there parts to the secondary pump through the governor side?

i put the tranny back together and it ran exactly the same. can go from 1st to 2nd but not to 3rd or 4th.

i dont mind dropping the tranny and replacing somthing if need be, but id like to know what parts to buy. or if there is a simple fix for the problem i am having.

this whole project started with "flaring" and then while adjusting modulator and bowden cable....bam! no more shifting to 3rd and beyond.

i am going to document my repairs in detail with pictures next time for all of you guys and anybody else who may have issues. i have made many "special" tools for this merc and people will really dig some of the things i have done.

I am not a tranny guy, but very capable. help!
