that PPI probably cost 2-300. By then u almost can go look for a normal one.
when buying a few hundred $ car, u need to run a very tight ship, every $ u spend could be gone forever. and save the mulla for more pressing items.
Is not the case of rebuild her to fact spec.

Try the Holy holy Lucas trans oil, as many had swore by that.

Many yrs ago my Audi 5000 suffer fromt he same fate, didnt want to go into 3rd. I drove 10 miles to work, the first 6-7 will only stay in 2nd.
Then suddenly it will pop into 3rd. Those were the pre-Lucas days.


U can always go to different tranny shop to ask for opinion, some being more hard up for biz could do a repair for less mulla, and some not hurting will sell u an outright rebuild.
Valve body coming out is less $$ than whole trans coming out, your issues could be a stuck spring, valve in the VB.

I had 1 toyota camry vee 6. that when cold if i leave her in OD she will shift into 3rd with no power, as if in neutral, if I hit the OD lock out button she will run nicely in 3rd. If i do that for few miles she will engage if I unlock the OD.

In the end i decided to sell her because of the heater doesnt want to let heat comes out. They have a reverse monojet valve than MB.
MB when no power going thru the hot water will keep passing, whereas this toyo will stop all hot water, as car were designed for Japan & tropical area so better no heat than scorching heat!
