which would be better? i have read alot on the TH400 but recently came across a Torqueflite 727 for a good price and was recently rebuilt by Jasper, but i do not know much about this particular transmission. whatever i choose will go in an 87 wrangler with a 258, dana 44's and be mated to a dana 300. i have heard both have efficiency issues and the 727 has heat issues?? but i dont know if these are true or just rumors. just let me know what you think or would recommend. thanks in advance fpr the input
