Delayed shifting in Transmission

Had to replace engine after 144,000miles with used engine 36,000 miles. Transmission is delaying in shifting unless you ease off the gas and then will shift. Engine seems to idle too high. Trans. fluids changed After driving 50 more miles the engine light came on and took to Autozone to have scanned. PO441 Trouble code. Replaced vapor canister. Didn't help but was clogged. Does the PCM software need to be updated?

SOURCE: 00' Kia Sephia LS not shifting past 1st gear

first you need to buy transmission fluid new filter and new need 11.4 pints of transmision fluid.raise front of vechicle.set parking brake.block both back wheels.besure support vechicle weight with jack stands. get a drain pan.if your transmission pan dont have a drain plug.loosen rear pan bolts a few turns.remove the front and side transmission pan bolts. let fluid drain.remove tranny pan. then clean old gasket material from transmission and pan carefully.dont scratch or damage surface.clean old tranny bolts using brake cleaner or buy new tranny have to put a tiny film of rtv silicone on tranny bolts so they wont leak.carefully remove old tranny filter and put on new filter.clean all grease grim away from tranny pan it should be **** and span might need a little gasket adhesive to hold gasket in place while putting pan back on line up bolt holes.loosely put all bolts in you have to move pan a little to get holes line up.when all is finish put tranny fluid back in.besure you put 11.4 pints back in that about 6.5 quarts. make sure tranny fluid level is right before driving vechicle.l

Engine shifts but rpms stay high

Your car acts like it needs a transmission service.That's where you should start. GM cars can act like the trans is shot when all it needs is a new filter. I don't understand how the dealer could miss it, though. Get back to me and let me know.

P1776 is the only code you need to be concerned with it a problem with the solenoid back (not the transmission valve body) Also did you recieve the transmission reflash that the dealer are supposed to do? And this is why you are dealing with a delay engagement (by the way its not second gear its 3rd)

Transmission Delayed Engagement

This bulletin involves replacing the front pump assembly in the transmission and checking the Transmission Control Module (TCM) for the latest software revision level.

2002 mirage tranny delays shifting does not slip.Tranny fluid is full.Has 150,000 miles on it.

Hi there,

Mitsi transmissions are programmed for smooth gear changing and a brief delay is normal.

However, if the duration of the delay exceeds 2secs, then there is an internal problem with the transmission.

You need to run the diagnostics on your vehicle (the PCM controls both Engine + Trans electronics) which will determine where the fault is ocurring.

Most likely causes can be:

- Abnormal underdrive clutch pressure
- Malfunction of the underdrive solenoid valve
- Malfunction of the inderdrive clutch
- Malfunction of the valve body (which houses all the valves & soleniods etc)
- Malfunction of the idle position switch

Your Mitsubishi dealership can use their MUT-II scan tool query the solenoid.

Fluid - condition of fluid is critical for acceptable operation:

1) ONLY USE MITSUBISHI ATF FLUID - never use other brands.
2) Check fluid colour - must be nice RED colour. If black, then fluid is bad - change fluid.
3) If fluid smells burnt, then fluid should be replaced (burning smell can be a sign of internal damage).
4) Fluid level should be checked while trans is warm & idling in Park.
5) NEVER overfill the trans - overfilling can cause the excess fluid to foam, causing shifting problems.
6) Although manufacturer recommends changing fluid every 70,000 miles, it is always safer to maintain clean fluid by changing every 30,000 miles.

Sounds like a bad speed sensor. Perform an ODBII scan soon. ECU should delay upshift until coolant temp senses warm up. It will not work right unless a signal is present from speed sensor.

I have a 1996 chevy silverado 4wd with an automatic transmission that has 180,00 miles and had the transmission rebuilt at 145,000 miles. From first to second gear it wont shift unless you left offf the...

Put a line pressure gauge (or visit a local trans shop) on the pressure test port and go for a drive to verify proper line pressure. Base pressure at idle in P,N,OD should be around 70psi and around 140psi in R. Max line pressure should be at least 190psi at WOT in 1st or 2nd, 225psi is optimum. If base pressure is low, trans or pump is worn out. If max pressure is low, check EPC solenoid. If reverse is slow to engage, and line pressure does not come up to at least 130psi in reverse, replace the boost valve with a Transgo 0.500" boost valve (easy fix in pan)
1-2 shift does not happen at WOT until you let off the gas: Best case: try replacing the TPS. Middle case: leak in the 2nd gear apply circuit (servo assembly or 1-2 accumulator). Doublecheck by using the pressure gauge and watch for a big drop when the PCM commands 2nd gear. Worst case: poor line pressure rise
1-2 Shift shudder at WOT; delayed or abnormal 1-2 shift; There's a problem ONLY on the 1-2 shift: 1-2 accumulator piston cracked or stuck cocked in the bore. Check the yellow spring inside the accum housing for breakage. Also, if the accumulator housing walls are scored, the housing must be replaced. Easy fix in the pan.
1-2 shift is delayed and harsh, may not shift into OD: Check TPS for smooth and linear electrical response over the entire range of motion. If not, replace.
Good luck and suspect the first two problems mentioned above. Thank you for suing fixya

Definitely something wrong within the transmission. Hondas have never been the smoothest shifting transmissions, especially with some miles on them. What you are experiencing is beyond that though. Get a second or third opinion from different dealers.

4T65E transmission hard shifting- can I drive it?

I had a 1995 with the same problem... perfect when cold... slams the gears when warm. I had to have it overhauled. I got by for a long while by up ******* manually, releasing gas pedal just before each shift.

Car shifts hard (up & down), especially shifting to reverse.

that delayed reaction may be the transmission slipping. with those many miles it could be the transmission going bad
