trans prob

[tankie88]

About 6 weeks ago i had the trans out of my 85 M1009.Only moved it back 6ins and tilted it back slightly to fit a new flexplate.Now the thing changes from 1st to 2nd normally and quickly into 3rd.It will kick down but not stay in the gear it kicked down to.Also if comeing up a hill it won't change from 3rd to 2nd on it's own,i have to change down manually.Anyone any ideas???????

check your vacuum lines.

The modulator line from the vacuum pump, or you may have bent the modulator on a cross member...nuffin serious

Well i checked all the vacuum lines all ok.Even took off the line at the modulator while the motor was running,it's suckin ok.Ideas?????

Is there a kickdown cable going to the trans? If so, check the adjustment at the throttle. I have seen these cables broken also by trying to sneak a flywheel in and not disconnecting them.

Hopefully you have the kickdown cable adjusted correctly.

There is no kick down cable,it's electric.Could the modulator be broken??

 

[CCATLETT1984]

Yes the modulator could be broken, Any local trans shop should have the part in stock.

hi , is it a th400 ?
i tried for my th400 the tm35 modulator. it works perfect.
the modulator shifts the gears soon and soft.
