Two automatic transmissions were available in 1986. Three speed automatic (says PRND21 on shift indicator on dash on console) is a Turbo Hydramatic 125C (TH125C). Later models it was called the 3T40. Four speed automatic (says PRN@D21 on shift indicator, and says "AUTOMATIC OVERDRIVE" in tinier letters over that) is a Turbo-Hydramatic 440-T4. Later models had the 4T60 which is a different transmission entirely.

You proble need a new Trany I would check you fluids ! Check all lines and plugs for the Trany.
It'll require an adaptor
In an automatic transmission this usually means the trany is low on fluid or the trany has internal problems.
i have a 2002 chevy avalanche1500 had transmission fluid changed about 3 months ago i just noticed a little slip and checked the trany fluid it is 2qts over can that hurt the trany and what type of fluid is required
yes it will work you will be geared low
Trany shot replace
Trany is short for transmission.
Probably the trany cooler in the rad has let go. If this is the case then the coolant is in the trany also. check the trany for coolant and if it is you will need a trany very soon. I've tried flushing the trany when this has happened in the past and have yet to save a trany. Usually within 3-6 week the trany stops working.
no 998 trany has different sensors and diff shift points the computer wont no when to tell it to up shift or down shift
small leak at the cooler lines and now you are down about oen quart of trany fluid
trany pan is the oil reservoir for the trany. Also provides access to the filter, valve body & trany internal components
