Transmission fault Caravan 96

What type of transmission uses the caravan 96 I have the problem that remains in 2a does not enter the third and what kind of oil can I put barely bought it a month ago. THANK YOU.

I would recommend that you take it to the workshop of a mechanic that fixes transmission boxes.

The caravan comes with two types of automatic transmission, one governed (hydraulically controlled) and another electronically controlled, such as differentiating, near the tube to measure the transmission oil you will find a box (control solenoids) with a square connector with approximately 6 cables and under that box there is also a series of 6mm exaggeal plugs. (Hydraulic test ports). That is electronic transmission.
The governed transmission lacks that box and the caps can be observed with the naked eye.
If a change in hydraulically controlled transmission fails, it is generally due to a failure within the transmission and you must disassemble it to serve it.
Electronically controlled transmission confine you must have the technical information to prove first if the failure is due to a poor condition solenoid, a defective speed sensor or the same TCM (transmission control modulate) this causing the problem.
Governed transmission Oil Dexron III
Electronic transmission Mopar or ATF+4

Thanks for the information I'm going to checked it with more advice on caravan? THANK YOU.
