Shifting troubl

Hello, I need help. 95 4runner v6 auto 2wheel drive 225,000 miles eng runs great. Having trouble with trans .I can shift into 1st gear, drives great, reverse gear drives great. It has no other gears, can't even get any other gears shifting manually, put new trans filter and fluid,. Tried adjusting TP sensor,. No change. Anybody have a similar issue,resol

 

Is it throwing any codes?

 

Honestly, I don't have a scanner or reader, I've always had older vehicles like 70 Chevelle,67 Camaro,etc...I was hoping to get an idea without having to go buy one ,but thinking I might now have too

 

I am new to the 4runner world, even though it's not on the road rite now, I still love it

 

I am not sure if your 95 is ODII or OBI. You may wish to find out before buying a code reader.

 

I believe originally it's ob1,but, I found an adapter in glove box and it plugs into vehicle,and the ob2 plugs into the adapter,I will get a reader in 3days, I will be out of hospital then. If I can get a code I will definitely relay it to you. I do greatly appreciate you conversing this issue with me and I do thank you in advance for any info/advise you may provide

 

I can't find the diagnostic plug so I could check for codes. Do you know where it is. ??95 4runner

 

Check the engine bay next to the fuse box according to google.

 

Before you buy a code reader try this.
