1-What controls the movements in a 4L60E 4L80E and would i be able to supplant the PCM with a vacuum modulator?
The appropriate response is the PCM is in finished control of each part of when and how the 4L60E movements, Line Pressure and Lockup. In the event that the order is given notwithstanding any mechanical disappointment grips, Band ETC the transmission must cause the move or slip and to consume itself attempting. On the other hand It can’t move before its told.
Lockup again is carefully a component of the PCM turning on the lockup solenoid and beating the PWM solenoid.
I hear many individuals state my converter secures now and then and other not what’s up with it. Well If your converter secures appropriately whenever. At that point its without a doubt a tuning issue and not a TRANSMISSION/CONVERTER issue.
On the matter of the vacuum modulator, It can’t supplant the PCM it just assumes control over the PCM capacity to control line pressure’s. I have many individuals inquire as to whether I do the “vac mod” will it fix my day of work timing issue? The appropriate response is no.
2-Shifts become milder or slipping after a converter introduce.
No in reality the movements continue as before as before the converter introduce. They feel milder as a result of the converters move expansion/detachment. The transmission it self is doing precisely equivalent to it did before the converter. Presently It can be beneficial to firm the movements up since more force is being moved however the trans at WOT.
3-Increasing line pressure in tuning is a decent method to solidify shifts.
Well it will firm the shifts yet at a cost of more strain on the hard parts and more noteworthy burden on the siphon. A typical disappointment for example to raising the line unnecessarily can be the disappointment of the information drum at the 3-4 grip snap ring or even siphon disappointment because of the additional pressure. There is even the chance of having so much line that there are sufficient cross holes to mostly apply grasps or groups when they ought not be on. As I would see it the best possible approach to improve move quality is to introduce and move unit. I have no inclination to type since all I have seen with just minor varieties achieve the objective less by raising line yet by expanding the rate or volume of liquid being provided to the grip in a given time.
4-Synthetic liquid will make your transmission slip.
I will probably get some flack on this one however this has not been my involvement with least not with liquids that meet or surpass the prerequisites for that specific application. This means the item paying little mind to type or brand must meet the base prerequisites it indicates. For example in the event that it says meets or surpasses dexron/mercron prerequisites then it must perform equivalent to or superior to the details of that liquid. Presently don’t think I imply that everybody ought to go purchase manufactured on the grounds that actually I think its overrated for what you get. The main genuine bit of leeway I have seen is the capacity to with stand heat better than oil based items. Nonetheless in the event that you have sufficient cooling this ought not be and issue at any rate, IMO utilize the liquid you like or what your converter or trans producer requires. We have no prerequisite here.
5-TRANS Fluid can get to cold and gel at below zero temps.
No it can’t in any event not at any temperature where individuals can live. Consider it thusly on the off chance that it could, at that point in Canada or Alaska the liquid would be gel in the dish in the first part of the day on fire up and would clear the siphon out right away. I have poured liquid from a container at – 5 degrees and keeping in mind that it’s only a little thicker it’s surely not gel. Transmission liquid is made to have a truly steady thickness at all temperatures. I am certain like all fluids there is where this could happen yet none I have seen.
6-Allowing a transmission to set either in or out of the vehicle for broadened periods (months/years) can bring about disappointment.
Truly really it can. As 4l60e transmission sets for extensive stretches of time liquid will gradually flee from the grip and hard parts. The seals can even dry decay like the manner in which tires do and more in clammy atmospheres dampness can enter and cause rust on hard parts and much under the covering of the grating materials and cause them to isolate. I have heard the “It worked incredible when I took it out 2 years prior story” and its reasonable a genuine explanation just to hear later that somebody set it back in and it kicked the bucket in days or weeks or slipped or other astute misbehaved from clingy valves. My recommendation for putting away a transmission for any time allotment is to plug all the gaps and fill till the liquid starts emerging from the flood tube. At that point top this to as that will safeguard all parts are lowered in liquid. You will simply need to deplete before restarting after capacity. This may help stay away from some post I see with transmission objections in the wake of removing a vehicle from capacity that has been setting all winter. Further details click cash cars buyer.
