I have a 2001 Jimmy v6 4x4 and the transmission pan gasket was leaking. After replacing it and adding the proper amount of fluid i started my truck and now its leaking from both the dip stick seal and where the cooler lines enter the transmission. Any ideas on what would cause these leaks to occur?

When it comes to changing the tranny fluid there's usually only 2 options. If your pan has a drain plug, remove it same as you would when doing an oil change. If not, you have to remove all the bolts on the pan to drain and replace it.

my car was leaking very bad transmission fluid do to my transmission pan so i took it off cleand it up. and found that the pan was a bit warpped and added silicone to new gasket and that fixed my problem for the pan. then i also had to replace the inner and outer seals and now my car dont leak transmission fluid anymore :)

What vehicle?
What leaks?

There is no reason to replace anything but the
pan gasket or side case drive axle seals, if you have a front
wheel drive transaxle

You have to get under these vehicles & provide
some info.

raise and secure on stands. loosen transmission pan bolts one at a time, starting back to front. do not completely remove them just yet. have a bucket or pan ready to catch about 1 gallon of fluid.when all are loose gently pry downward on rear of pan to break seal.careful..fluid will come out at this point.one at a time remove rear bolts to allow pan to drop a little at a time.once pan is removed,remove old filter. clean pan and all mating surfaces. make sure there is no oil or grease on gasket surfaces. install new filter and filter gasket(small round rubber gasket).install new gasket and pan. tighten bolts evenly but dont over tighten.refill with clean fluid and check for leaks.make sure to check fluid level after each quart is added. engine should be running to get proper reading.too much or too little can damage your transmission.

transmission filter in the bottom of transmission bolted to valve body.you need a large drain pan.place drain plug under transmission oil pan.remove transmission oil pan drain plug.let all transmission fluid drain out then screw back drain plug in oil pan.then you need to remove transmission oil pan then remove filter and replace pan gasket also.make sure you have right amount transmission fluid on hand.buy extra because if you short of fluid you cant drive car if fluid level too low.make sure you get the right amount fluid.torque pan bolts to 96 inch pounds.

TRANSMISSION FLUID LEAKS,CAN BE FOUND AROUND PAN GASKET.CHECK PAN GASKET,IF IT LOOKS WET AND YOU SEE FLUID DRIPPING AROUND THE EDGE OF OIL PAN, REPLACE PAN GASKET, WHILE YOU REPLACING PAN GASKET REPLACE TRANSMISSION FILTER WHILE OIL PAN OFF.IF TRANSMISSION OIL PAN NOT LEAKING, CHECK TRANSMISSION OIL COOLER LINES GOING INTO RADIATOR YOU WILL LOOSE A LOT OF FLUID THERE ALSO TORQUE SHAFT SEAL WILL CAUSE HEAVY FLUID LEAK WHILE ENGINE RUNNING CHECK OIL COOLER LINES AND LOOK AT THE TORQUE AREA WHILE ENGINE RUNNING YOU WILL SEE FLUID POURING WHILE ENGINE RUNNING THE OIL PUMP PRESSURE WILL PUSH FLUID OUT AT THE LEAKING AREAS.

Transmission fluid is drained by removing the bottom pan off the transmission. There is no drain plug. If unobstructed by a crossmember,support or the exhaust, you can do this your self. Obtain a filter and gasket set, 1 can of brake cleaner, and 1 gallon of recommended transmission fluid from local parts store. Remove negative battery cable. Raise and support front of vehicle using jack stands or ramps. Set parking brake.

Loosen bolts 3/4 way around pan and put a catch pan beneath trans. pan. Slowly loosen remaining bolts until fluid begins to drain from 1 corner, loosen as it drains until you can remove pan. (its messy no matter how careful you are) Clean pan out well using brake cleaner. Clean outer rim/gasket surface of pan and mating surface of transmission thouroughly as to leave no evidence of old gasket or sealant down to shiny metal. You can use a bit of fine sandpaper or steel wool to help. Do not oversand. Clean all surfaces completely finishing with a wipe off using brake cleaner, make sure pan and trans. mating surfaces are dry and free of fluid. Install new filter in transmission, then gasket and pan as advised by instructions in filter/gasket kit. Re-fill transmission fluid through dipstick hole marked TRANS or TRANS FLUID in engine compartment using a funnel in dipstick tube. Put in about 2 quarts, then start engine in park on level surface. Put in SMALL amounts of fluid , re-checking level continuously until proper level is reached. Drive car 10-20 miles and re-check fluid level again, add accordingly. DO NOT overfill transmission, as seal damage will result. If you overfill, drain small amount off by loosening pan bolts slightly and jacking up one side of vehicle to make gravity force some out. Let us know how you do :)

loosen bolts on bottom of trans pan, pull one corner lower than others, drain fluid into large flat container. Remove gasket and filter. replace both. replace pan cover careful to keep gasket in position. check owner manual for amount of fluid to fill and type of trans fluid. DO NOT OVERFILL- EVEN 2 OUNCES OVER CAN RUIN SEALS

Get new fluid, pan gasket and filter.

Put vehicle on ramps.

Starting at one corner, use ratchet to loosen and remove bolts from pan. Be sure to have a drain pan directly under the corner that drops to allow fluid to be collected. Do not remove any bolt before loosening all the bolts first, and slowly work from the same corner. You do not want to bend the flange on the pan.

Drop pan out of the way, remove/clean away old gasket, clean up pan, and pan bolts, apply light coating of gasket sealer to flange and apply new gasket.

Remove and replace filter. Check pan mating surfaces on tranny and make sure they are clean.

Reinstall pan into place by starting all bolts before tightening. DO NOT OVERTIGHTEN BOLTS OR THE PAN WILL LEAK! Rotate around the pan, tightening each bolt slightly to no more than about 10 ft ponds of torque. A 1/4 inch ratchet is best used for this procedure.

Refill tranny with the amount of fluid removed into the drain pan.

This procedure will not replace any fluid in the torque converter, and generally most vehicles have no way of changing the torque converter fluid.

in my opinion if the car is changing gears fine then just fix the gasket and seals when you can if its changing fine then they are trying to rip you off as renewing the seals and gasket will fix your leak and if its slipping gears it could last a day it could last a year so if its slipping yes its important to replace it
