so....was it just low on fluid,or a bad filter?glad you got it going either way! now to get going on the brakes!g'luck.
it was just low on fluid. now i just have to fix the brakes and it will be driveable thanks for the help!
From what I have seen nothing. Transmission fluid is just that Transmission fluid. They just add different additives to make it shift smoother, hence Dexron3, Mercon 5, Chrysler 3, yada yada yada.........I run dexron 3 in my c4 no problems.
The deal is in the friction material in the tranny... Type F has the most "friction modifiers", while the others are more and more lubricant. Ford trannys needed the friction adders to make the clutches work correctly. Todays trannys use different internal friction materials and use more slippery fluid. You can add the friction fluid to modern trannys to get less slip and hard shifts, but to take the friction away from early trannys is to slip the clutches and/or bands excessively and wear quickly. Consider a clutch type 'posi' differential. It needs the same friction modifiers to work properly and last. If you just run gear oil, the clutches won't last as long.
You are exactly wrong in your thinking. Type F has less friction modifiers. The friction modifiers are added to make the shifts smoother. In reality firmer shifts help extend the life of the clutches. The manufactures however had way to many complaints of harsh shifts from customers over the years who percieve harsh shifting as sign of transmission wear. I add friction modifers to Mercon/Dexron III to convert it to Mercon 5 at work. There are many internal changes as well to newer transmissions. I donlt have time to go into at the momenet it's of to work
Well, maybe I was 'backward', not wrong. All I know is that the friction materials and fluids must be matched for a tranny to live long. The fact is that type F trannys must have type F, while other trannys can use type F without issue. Type F is the universal donor. Dave
Dave again I would disagree with this. If you put Type f in a newer crown vic you would end up with torque converter shutter as a minimum and likely burnt clutches. Sorry if It I sounded harsh on the other post I wasn't trying to be.:Handshake
Oh, I know you weren't being ill to me. I was j/k. Yeah, you are probably right about the converter shudder... I forgot about that. I had read up on it recently. Dave
Well, B&M Trick-Shift fluid is nothing more that Type-F with blue dye instead of red. it is used in GM and Chrysler transmissions. So if Type-F is bad for trannys that originally used Dexron/Mercon, why would B&M recommend their product for more firm shifts? Wouldn't there be some liability there? I know you cannot use Type-F on the newer trannys, but I'm referring mostly to late '60s to early '80s trannys. I know a guy who mixes Type-F with Dexron/Mercon for his '700R-4 in his third-generation Camaro...
Everybody keep an open mind about this because there are a lot of parameters to consider overall. The C4/c6 from the factory used type F as did the power steering pumps all the way into the 90s for the pumps on some cars and trucks. The fluid type is predicated on the band and clutch material and design vs life to the consumer. That does not mean that no other fluid will work.Type G fluid like used in Europe, used in a C4 would make the shifts more harsh. As time went on and the AOD came about, the fluids were modified with additives for lubrication, smoother shifting and different friction materials so the answer is 'it depends', for fluid applications. In the 90s the AOD, AODE/4R70 specified Mercon then later the same units (4R70) were speced to use Mercon V which is Mercon with another additive. Only Ford uses the V type and you can see it is not in abundence on store shelves, most places. Even when rebuilding a transmission the the builder could put in different friction materials and also specify a different fluid than OEM. This often is done on performance rebuilds as a special application and has to be understood as such by the user. About any fluid put in will allow the transmission to operate but the question is at what life expectancy and overall performance per the application. You can hear all kinds of stories about mixing and using types other than the spec in different transmissions, question is would you do it? I know for warrenty it dosent fly with a dealer/vendor/rebuilder when a problem developes. The shudder problem is most associated with electric lockup type transmissions where the converter has friction material that gets into a 'grab-release' action that is percieved as the shudder. These transmissions lock and unlock an unbelievable number of times while driving so the fluid type, temp and contamination become a sensitive issue. There are other faults that could be percieved as shudder involving the clutches. One example of unlock is just the application of braking will unlock this converter. If throttle is reapplied it locks up again. This is all by design since the first ones were used in the mid 80s. Most drivers never feel this action it is so smoothe. A vehichle with a tach will show the tell tale sign if the driver is watching close enough to see it.
The guy that built my tranny (C4), put in Dextron/Mercon when he finished, and I have had it in there for 6yrs. Still works fine. But....would the trans work better and last longer if I changed it to type F? Just wondering. Need to remove it to plug up some leaks and put in a new converter.
Earl, I have Dexron/Mercon in mine to. My grandpa has been using it in C4's for years with no problems. It says on the back of every bottle I have ever bought that it's fine to use in transmissions that require Type F. I would think the people who made it would know best...
