Have a 2005 JD LT190 with the Tuff Torque K46 transaxle in it. Tractor and trans has been perfect no issues all these years. Decided that this year that between mowing season and snow plowing season I would drop the transaxle and refresh the 9 year old trans oil.
Dropped the tranny from tractor drained, refilled with syntec 5w50. Reinstalled and ops checked it. Tractor will now barely move. Apparently it needs the air purged from the hydrostatic unit. I tried the instructions from Tuff Torque with no results.
Here is their procedure:
1 Check oil level.
2 Place vehicle's drive axle on jack stands with wheels off floor.
3 Start engine and operate at low idle speed.
4 Repeat opening and closing bypass (tow) valve while alternately depressing forward and reverse pedal(s).
5 When vehicle starts to move, increase engine speed.
6 Repeat quick starts and panic stops until transaxle gives full response.
7 Remove jack stands while placing vehicle's wheels on floor.
8 Recheck and top-off oil level.
I consider myself mechanically inclined and college educated but I cannot understand these instructions. Particularly step 4.
On step 4 do I depress the forward pedal then while holding it down engage and disengage the bypass lever?? Then depress the reverse pedal and engage and disengage the bypass lever again??
Do I then repeat this several times??
On step 5 how can the vehicle move if it's on jack stands??
On step 6 how can I make quick starts and panic stops if it's still on the jack stands??
If anybody has any info/suggestions on this procedure I would MUCH appreciate it!!
Trying to get this done tonight, before I call Tuff Torque tomorrow. Tom
