I am getting OBD code P0700. That is all what my scanner reads. What kind of scanner is needed to get more info from TCM?
Really that is all you need unless you want to spend $200 on a better scanner. Post that code on line and you will get the problem and fix suggestions. Or purchase a repair manual (Haynes) which has the codes and sensors listed but leaves the repair solutions to you. Remember that a code can be caused by more than just a bad sensor so be careful.

OBD 1.5
OBD 1.5 refers to a partial implementation of OBD-II which General Motors used on some vehicles in 1994 and 1995 (GM did not use the term OBD 1.5 in the documentation for these vehicles - they simply have an OBD and an OBD-II section in the service manual.)
For example, the 94-95 Corvettes have one post-catalyst oxygen sensor (although they have two catalytic converters), and have a subset of the OBD-II codes implemented. For a 1994 Corvette the implemented OBD-II codes are P0116-P0118, P0131-P0135, P0151-P0155, P0158, P0160-P0161, P0171-P0175, P0420, P1114-P1115, P1133, P1153 and P1158.[1]
This hybrid system was present on the GM H-body cars in 94-95, W-body cars (Buick Regal, Chevrolet Lumina ('95 only), Chevrolet Monte Carlo ('95 only), Pontiac Grand Prix, Oldsmobile Cutlass Supreme) in 94-95, L-body (Chevrolet Beretta/Corsica) in 94-95, Y-body (Chevrolet Corvette) in 94-95, on the F-body (Chevrolet Camaro and Pontiac Firebird) in 95 and on the J-Body (Chevrolet Cavalier and Pontiac Sunfire) and N-Body (Buick Skylark, Oldsmobile Achieva, Pontiac Grand Am) in 95.
Depending on the year and the vehicle, a car with the OBD 1.5 system may have either the older OBD-I connector, or the newer OBD-II connector, but they are electrically identical to each other.[citation needed]
The pinout for the ALDL connection on these cars is as follows:

16
For ALDL connections, pin 9 is the data stream, pins 4 and 5 are ground and pin 16 is battery voltage.
Additional vehicle-specific diagnostic and control circuits are also available on this connector. For instance, on the Corvette there are interfaces for the Class 2 serial data stream from the PCM, the CCM diagnostic terminal, the radio data stream, the airbag system, the selective ride control system, the low tire pressure warning system and the passive keyless entry system.[2]
An OBD1.5 has also been used on Mitsubishi cars of '95 '97 vintage.
An OBD1.5 has been used in some 1995 Volkswagen VR6's (Juice Box's GTI)

I had the same problem and a friend suggested that I get a filter kit for the transmission. My dodge ram 1500 stopped pulling and had to be towed home. I got a filter kit for the transmission and now the truck is runniing good again and the transmission is shifting ok.To get the code off by going to
Auto Advance and used their code reader to erase the code. My truck has 249K on it and I know the trans will not last forever, but as long as it is running ok. I will live with the codes but make sure the trans fluids are changed every 10k.

The code readers have changed along with the standards relating to the depth of info provided by the ECUs; you will need to use your model year to shop one and do shop it; the prices of these things vary greatly and the simplest will do what the typical owner needs done; read codes.
You'll find numerous vendors on line and they range (overall) from ~$20 to $250+ US.
I've not seen any connectors that were not located on the driver's half of the car; they are a flattened 'D' configuration, have always been mounted horizontally and have two rows of pins.
Some are concealed under a slip-off plastic cap.

Funny, but I realized my cheap scanner gives more codes when switching ignition key to RUN and ON positions. When in RUN, I got this P0700, only. But turning to ON and rescanning, I got more codes, P0841, P0731, P1776 and P0871.
I did change filter and fluids. And reset all codes. those came back after 15-20 min drive. So, same problem. I did check wires and all closed and open to ground and voltage. Everything was OK. Next step is to buy new solenoid pack I guess?
