If your sienna is the 97-03 model year

1. Go and look for Total MVLV @ 3500/L you will need 4 litres

2. Let the mechanic open the gear sumo, clean out the strainer and watch out for matallic chippings on the magnetic filter, if none good, he should clean and drain out the oil he put there.

3. refill the gear with the total and retest the vehicle.

4. if there is a positive difference good if it's slipping (gear engages and disengages and refuses to leave gear 1) go and buy a new gear.

5. Don't use any dextron 3 for that gear ever again.

Sir. Help my life. Spent 20k already on this Gear.
My problem is similar to what the OP said. But here is the picture of what I am going through.

I took my Sienna to mechanic for gear oil Change. after noticing some drags and sudden change in acceleration. The mechanic said the oil was burnt. I did notice some iron fillings on the filter during the servicing. The mechanic said it was a non-issue. He washed clean the filter and replaced the gear with Oando dextron 3 gear oil-I just hope I am not mistaken. The oil is sold for 3800. I drove the car to the wheel alignment and balancing shop to check since I will be Traveling on the third day. After checking the alighnment and stuff. I reversed out. put it on drive. Nah so my condition start. it won't engage in drive nor reverse. Towed it to the gear mechanic. He checked it and said the drive was bad. changed the drive. Still no show. He removed and service the Valve body. Only the Reverse gear worked. Replaced the 9 pin valve body with a 5 pin Valve body. Took the car for a test ride. Selection from 1 to 2 is Jacky but rest selection was okay. The reverse gear engage but not enough power to move the car because When he raised one of the wheel. The gas pedal rolls the the wheel in reverse but not when the four wheeler are on ground. He later discovered car reverse stops working as car gets hot. please, What can I do?

At this junction best decision is to replace the gear with Tokunbo

Thanks for the quick response. I am grateful. Please wat is the price estimate?
Do you still drive your sienna? Mine is 2002 model. What oil(gear and engine) is recommended because I think the oil use must have contributed to my situation. And Radiator coolant. I have been doing the unholy act of using water. Can my ignorant action still be redeemed. Do I need to change the whole radiator. Or just switch back to using coolant.

It should be between 90k and 120k because your 97-00 is different from 01-03

I use MRS 5W40 full synthetic since I bought mine 6 years ago

I used Total MVLV dextron 6 for my gear, the Oando dextron 3 flares the transmission when it is hot like 2hrs driving. Alot of high mileage sienna I personally know experience flares and some packup especially with cheap ATF usage. transmission aren't like Engines at certain high mileage it's unusual to start experiencing failure.

my radiator coolant is the one total sells for 450, the green one, been using it since 2017, I haven't had time to drain it and refill but will do that when I get opportunity

As long as the radiator isn't blocked or leaking, just drain the whole water and buy 5L of coolant, pour about 3.5 to 4L and use the remaining to top up after driving.
