I buy a bolens ht 20 (with sundstrand 15) with a transmission problems.
The transmission slip and run slow sometime reverse or forward.. I flush oïl and replace for new ATF type F oil and new filter. After that the tractor drive better but not perfect... I take off A valve in the transmission and the spring is broken , i replaced by a similar but not identic spring and the problem is reduce but not completly (The tractor move more faster and slip sometime when i play hard with the pedal)
Also the tractor has no neutral, the wheel turn in reverse and sometime in forward none stop ( i press a little bit on the pedal for the tractor rest in place) I try to adjust the linkage but no succes. Maybe because a valve is not good and do the wheel spin ..
What do you think? The new spring is not good or a other problem in the transmission?
Thank you for your help and sorry for my English is not good..
when i remove the bolt for take a valve, the valve is disassemble in the transmission..
The spring is broken,the ball is loose in the transmission and the bolt is not in good condition..
I replace with new spring but is not the same..
The other valve is assemble and in good condition..
