Moin people, I’m not really knowledgeable about postings in forums, but I’ve already had the search engine ratter and found nothing on my topic, if there is something to do, I ask for a look and a hint… the following problem is up, I have an 80s 301 Trans Am. There had to be fixed some problems on the engine for that I didn’t lift the engine including the gearbox (Thm 350) out of the TH 350 C. After completion of the Engine and overhaul of the gearbox (change seals, insert new filters and replace oil, the converter has also come new and was filled with oil until it runs out of the scar in the vertical state Dexron3 standard) the unit was assembled outside first converter on transmission, this on motor and then the converter adjusted. Then kickdown cable and vacuum hose again connected with vacuum system or gasifier rocker. After that the unit was lifted again and ve The motor runs well with 700/min in the stationary gas and there is also no leak in the vacuum system. The transmission oil was filled up until the marking of the marking rod and measured in the course was inserted during the neutral. So I took it from sources. However, the transmission does not build up any torque or transmits it any further from the motor…the further is funny , that the oil cooler pipes do not carry any oil where there should actually be enough oil inside. however, I would not weather on it that the marking rod original of a THM 350 is that happens with such old boxes already. Well, however I have described the problem here once in detail , someone has had similar problems with this series since it is one of the most built gearboxes and was also installed in Corvetten etc. . Or someone knows someone de I thank you in advance and I am eagerly looking forward to Franky
