Question about 1992 Toyota 4Runner

1 Answer

Poor acceleration with A340H A/T on hills and onramps

My 1992 Toyota 4Runner 4X4 has a A340H transmission. When the timing is set to 19 degrees, I have acceleration up hills, and entering freeways. However, it will not pass smog. When the timing is set to 10 degrees, it will pass smog, but I have no acceleration, either on freeway onramps, or going uphill. Is there any alternative that would give me power and stay within smog specs for California? Would a different transmission correct this problem?

    I may have blown my engine because of this problem when I downshifted to try to get some power, then shifted back into drive to get up to speed.

1992 4 runner 4 x 4, I think it is already passed 150,000 miles.the pistons and rings are lose and are leaking, the pressure probably low, try to use some oil treatment, I used Market America special oil treatment and got a very good result. you can set to 19 degrees and add some of those treatment see the result, this is cheapest way, just try it, because I can not test drive your car and check the engine pressure.
Please be sure go to MarketAmerica.com and check it first.

How much tranny fluid do you need to put into the transmission of a 1991 Automatic 4Runner?


These are total capacities. You need to compensate for any residual fluid you have in your system.

I will list the transmission type then the capacity to the side of the transmission type. All transmissions take regular Dexron III fluid

A43D 6.9 qts
A340E 7.6 qts.
A340H 10.9 qts.

1994 toyota 4x4 22re loses power when you push gas pedal or going up hill and the valves start to rattle then


I suspect your ignition timing is too advanced and the rattling sound is actually detonation (VERY VERY bad for your engine). Have your ignition timing set and your valves adjusted.

4 runner reverse slippin


The bands in your transmission are on their way out.. It doesn't do it (as bad) in 4lo because of the low gearing.
Time for a transmission rebuild or replacement.

Torque settings


You have to use new headbolts because they are torque to yield bolts. You start in the middle and criss cross out to the ends with an initial torque of 33 ft-lbs. Then you criss cross out out again with an additional 90 degrees on each bolt, then you do it again from the middle another 90 degrees to make a total of 180 degress past the initial 33ft-lbs.
