The transmission in my truck is giving me problems. The 1 to 2 shift is normally very delayed and sometimes it will shift at the normal rpm. However, it will not do a 2 to 3 shift by itself at all. The only way it will do it is if I shift the transmission from N to D. Then 10 seconds later it will downshift again and I have to shift from N to D again. What should I check? Vacuum modulator is hooked up.
Off the cuff, does the modulator hold a vacuum? When's the last time you did a fluid/filter change? Devon
I will check the modulator. How is it removed? Fluid and filter change has never been done by me. I already bought the stuff to do it though. This wouldn't be the governor would it?
It has a hold-down bracket not too different than a distributor; 1/2" wrench will do it if I remember right. Doesn't sound like it. Devon
Get a vaccum guage and see what you have. Modulators are cheap. make sure the line is there and not cracked. Is kick down cabe hooked up? try the simple stuff first.the
Well, it was the vacuum modulator. Took it out and fluid poured out the vacuum nipple on its way to the trash can. Also did fluid and filter change, and failed for the third time to replace the shifter shaft seal. Last time I will ever drop a pan on a transmission! What a mess!:rant:
Transmission still is acting up just like before. However, it acted fine when it was cold, then when the tranny got up to temp. the problems came back. What gives? Sounds like rebuild time.
Most likely cause is either the piston seals or seal rings in the high/reverse clutch drum. Yep, sounds like rebuild time to me.
Yup, the problem came back. So what do I do? What any redneck would do with a beat up off-road truck, dump in another bottle of transmission fix. :laugh: Problem is still there, but it is tolerable on the highway and still runs great on the trails. Tranny shop wants $850 to pull and rebuild trans. Eventually I will let them do it but I don't want to spend that money right now.
