Installed new push belt, carrier assembly, transmission fluid and additive (6 qts. + small syringe of additive) Will pull slightly when cold, but will not pull when hot. possibly the transmission fluid pump? How or can that be checked without taking everything back down. Acts like the fluid is low....is that the correct amount of fluid?

Re: apparent low pressure on VT25E transmission
You can check internals by having a pressure test done on the transmission in car at an accredited transmission shop. With the modern transmissions and the new fluids used oil additives are not generally recommended as they stop the bands and clutch pack from binding up and working but increase the ability to slip and so not work properly/. Have the test done and discuss the problem with the shop experts.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

it's very special, and if done wrong, dooms the trans-axle
all this is covered, in the FSM
read it in the book and on most cars the CVT has very very
special needs and procedures for changing lube.
some, it must be done a s special temperature. < yes.
ever seen and FSM. (for doing factory service)
it shows all the steps, 1 by 1.

the lube is at GM. dealers.
VT25e (cvt made in Hungary)
GM RPM code M75(2WD)/M16(F4WD)
DEX-CVT and Automatic Transmission Additive
there are 10 service bulletins on this trans-axle
TSBs (read them all)
see the special additive yet>?
Use DEX CVT fluid (P/N 22688912) only. Use of
any fluid other than DEX CVT will
cause internal trans=axle damage.
Add one unit (10 CC syringe) of DEX CVT additive (P/N 22697447) whenever an unrecoverable loss of fluid occurs during an authorized limited on vehicle repair. Minor fluid
loss, such as minor drips that may occur during the fluid checking procedure, does not require the addition of the additive.
here is the actual instructions for replacing VT25e filter and fluid (special)
15 quarts is total capacity of transmission, toprque converter, lines and the cooling reservoir. What you would have to add if a new transmission was being installed.
8 quarts is the capacity if you were to drain the transmission on the car, like if you were doing a flush and refill, you take the lower transm. pan off and let all fluid drain, you will only get about 8 quarts.
First off, if it's an automatic transmission you DON'T put 90 wt oil in it! It uses automatic transmission fluid. Depending how low it's down it could take anywhere from 3 - 6 qts of automatic trans fluid. Have a shop look at it for you.
There is no drain on the radiator, loosen lower hose to empty coolant. Metal pipes are the transmission fluid lines. Coolant quantity for the 6 cyl is 14 qts, and 15.3 qts for the V8. If you have the extended wheelbase model, the quantity is 15.2 qts and 18 qts respectively.
This code is set when there is a variance in speed from the transmission input and output shafts. It can be a simple sensor issue or a more complex internal problem. There are several recalls for VUE transmissions but I do not think yours falls under this problem. Yours sounds more like an internal belt issue which Saturn has a technical bulletin for as shown below. This usually requires replacement of the case cover and filter and sometimes the belt depending on the damage. This is the bulletin that has to do with your code; Bulletin No.: 04-07-30-024E Date: June 09, 2006 TECHNICAL Subject: No Movement in Drive or Reverse with or without DTC P0741, P0742, P0841, P1756, P1758, or P1882 (Replace Case Cover Assembly and Filter) Models: 2002 Saturn VUE - Retrofitted with a 2003 or 2004 VT25E (VTi) transaxle (RPO M16/M75) 2003-2004 Saturn ION 2003-2005 Saturn VUEwith VT25E (VTi) transaxle (RPO M16/M75) Supercede: This bulletin is being revised to add additional Correction information. Please discard Corporate Bulletin Number 04-07-30-024D (Section 07 - Transmission/Transaxle). Condition Some customers may comment on the vehicle not moving in the "D" (Drive) or "R" (Reverse) gear selection positions. In many cases, the transaxle will also produce an audible grind or whine noise when attempting to operate in drive or reverse. The Service Engine Soon (SES) telltale may be illuminated with DTCs P0741, P0742, P0841, P1756, P1758, or P1882 set. Cause This condition may occur when the VT25E transaxle belt has malfunctioned.
Find out your engine size/type and buy the following: Engine belt, Spark Plugs, Spark plug wires, Oil filter, Min.of 6 qts oil, Air filter, maybe get a bottle of fuel injector cleaner, Fuel filter would be good(Get the ford A/C and Fuel line tool. usually $20), Maybe get a Lucas style transmission fluid additive, this should all cost $150-$200. and covers pretty much all the major areas of a tune-up.
If your vehicle has the 5.2 liter,aka 318 cubic inch engine,there is only one transmission model applicable and it is the 42 RE which used to be designated the A500.It is a 4speed overdrive transmission.If installing a rebuilt trans and new remanufactured dry torque convertor.You add 4 quarts initially,then fire the engine and add another 5-6 quarts for a total capacity of 9-10 quarts.Fluid level is checked with the trans in Neutral.If you are only dropping the pan,you will replace roughly 4 quarts.The transfer case fills separately,but uses the same automatic transmission fluid.Capacity for the transfer case is about 2 quarts/fill to the bottom of the fill plug hole.Good luck.
